What is the area of a rectangle that is 1 1/4 meters long and 3/4 of a meter wide? - A triangle 2
A triangle has a base of 2 inches and a height of 2 3/4 inches. What is the area of the triangle? - 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? - 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 - Area of a room
Find the area of a room 9/7 m and 2/7 m. - Runner training duration
How long will training for an endurance runner last if he plans to run 36 km at a speed of 5 m/s and spends 35 minutes warming up? - Train - start-up
A train weighing 1,200 tonnes is supposed to reach a speed of 15 m/s in 45 s when starting up. Determine its acceleration and the magnitude of the force it must exert if the friction force is 0.005 of the train's weight. - Shear friction
How much force must be applied to a box weighing 300 kg to move it at a constant speed along a horizontal floor, if the coefficient of sliding friction between the box and the floor is 0.5? - Additional Force on Body
A body with a mass of 5 kg moves in a vertical downward direction with an acceleration of a= 12 m/s². What force acts on it in addition to its weight? - Car braking force
What constant braking force is required to stop a car weighing 1 ton in 10 seconds traveling at 50 km/h? - Rail temperature expansion
How does the rail lengthen when the temperature changes from -30 °C to 30 °C if it is 25 m long at 0 °C? The temperature coefficient of longitudinal expansion is 12.10na-6Kna-1. - Grandmother house distance
Little Red Riding Hood walked through the forest from her house to her grandmother's house. She walked at an average speed of 0.75 m/s. She left her house at 11:30 and reached her grandmother exactly at noon. How far from her house does her grandmother li - Tourist route time
How long would a tourist walk the route if he measured 24.9 cm on a map with a scale of 1:25000? The marching speed is 4 km/h. - Dynamometer
What is the volume of a body that stretches a dynamometer in air, on which a force of 2.5 N suspends it, and if it is immersed in alcohol with a density of 800 kg/m³, does it tension the dynamometer with a force of 1.3 N? - A biologist
A biologist knows that the average length of a leaf of a certain plant is 4 inches. The standard deviation of the population is 0.6 inches. A sample of 20 leaves of that type of plant given a new type of plant food had an average length of 4.2 inches. At
