The height difference between points A and B is 475 m. Calculate the percentage of route climbing if the horizontal distance between places A and B is 7.4 km. - Catering business
The Montealegre family has a catering business. At one birthday party, they charged their customers $11,767.50 for a party of 90 people and a service charge of $2,500.50. What was the average cost per person? Please show your solution. - Bike distance
Places A and B are 30 km apart. From A, Peter will ride a bike at a speed of 18 km/h. Milo is also a bike from B but at 24 km/h speed. How far apart will they be after 20 minutes? - Aluminum volume expansion
The aluminum container has an internal volume of 0.75 l at 20 °C. How does this volume change if the temperature increases by 55 °C? A = 24.10-6 1/K. - To the city
A bus departs for a city 54 km away at an average speed of 15 m/s. A motorcycle departs from the same place 12 minutes after the bus to follow it. Calculate the average speed of the motorcycle if it arrives at the destination at the same time as the bus. - Tractor 17
A tractor's average speed was 2.4 km/h in the first minute of starting, 3.6 km/h in the second and third minutes, and 5.0 km/h in the fourth through sixth minutes. What distance did it cover during the first six minutes of driving? Determine the tractor's - Boat water speed
The water in the river has a speed of 4.8 km/h relative to the bank. A boat in still water has a speed of 12.6 km/h. a) What is the boat's speed relative to the shore if it is sailing downstream and upstream of the river? b) What path will the boat travel - Car braking acceleration
The car stopped at an initial speed of 90 km/h on a track of 62.5 m. What was its acceleration, and how long did it take to brake the car? - Power consumption
The price of electricity is ₱6.50 per kilowatt hour (kWh). How much electricity was consumed if a television with 120 W power consumption ran from 7:30 AM to 12:30 PM? How much will this cost? - Free fall 5
Jeremy accidentally dropped his toy stuffed animal from the balcony of his apartment on the fourth floor. The toy hit the ground at a velocity of 16.0 meters per second. At impact, it took 2.0 seconds for the toy's velocity to reach 0 meters per second. I - Bulb resistance calculation
The small bulb's socket has a reading of 6.3 V/0.3 A, which applies to its filament when the bulb is on. Determine the electrical resistance of the fiber under the given condition (the temperature of the fiber corresponds to about 2800 °C) - Self-oscillation period
The water in the vessel carried by the boy has a self-oscillation period of 0.8 s. What is the size of the boy's movement speed when the length of the boy's step is 60 cm? Give the result in m/s. - Cars Distance Before Meeting
From cities A and B, two cars drive opposite each other on the same road. The first runs at a constant speed of 80 km/h, and the second at 60 km/h. How far will these cars be a quarter of an hour before they meet? - Two airports
Two airports are 2690 km away. From the first airport, the airplane flies at a speed of 600 km/h, and from a second airplane at a speed of 780 km/h. When will they meet if they fly at 10:00? How far from the first airport? - An acceleration
The car goes on a straight road at a speed of 72 km/h. At some point, the driver starts to brake and stops the car in 5 seconds. Find: (a) the acceleration during braking and (b) the distance traveled during braking. - Plane Chase Time
A Boeing plane took off from the airport and flew at a speed of 900 km/h. When it had flown 600 km, a fighter plane was sent after it from the same airport, which flew at a speed of 2100 km/h. Calculate how long it took him to catch up. - Storm
So far, a storm has traveled 35 miles in 1/2 hour in a direction straight to the observer. If it is 5:00 PM, and the storm is 105 miles away from you, at what time will it reach you? Explain how you solved the problem. - Incendiary cord
The flame spreads along the incendiary cord at a 30 m / min speed. How long must the cord be so that the launcher can move to a distance of 200 m if it moves at a speed of 4 m/s? - Intersection - cars
The tractor drove through the crossroads at a speed of 36 km/h. Ten minutes later, a passenger car moved at 54 km/h. How long and at what distance from the intersection will the car run over the tractor?
