Kilometers - subway
A subway train covers a distance of 1.4 km between two adjacent stations in 1 minute 40 seconds. What is her average speed? Give the result in kilometers per hour and meters per second.
Replacement of resistors
In a circuit, 2 resistors are connected and a current of 350 mA passes through it. Between the terminals of the first resistor we measured with a voltmeter a voltage of 7 V and between the terminals of the second resistor 10.5 V. Your task is to replace t
On the Oval Track
Two runners are training on the oval stadium track. Both runners start from the same point and maintain a steady pace. The first runner completes 3 laps in the same time that the second runner completes 2 laps. Both runners set off in the same direction a
Circuit current calculation
We connect a 9 V battery, 2 light bulbs in parallel, and a switch to the circuit. When the switch is turned on, a current of 0.5 A passes through the first bulb and a current of 8 A through the unbranched part of the circuit. Draw the connection and calcu
Resistor parallel current
We connected two resistors in parallel in the circuit, with the first having three times the resistance of the second. The voltage between the terminals of each resistor is 6 V. Calculate the current through each branch when the resulting resistance of bo
Cyclist car overtaking
A cyclist traveled 50 km in 2 hours. A car followed him from the same city and overtook the cyclist in an hour. At what speed was the car going, and at what distance did they meet?
Create
Create a table and XY-graph for the presentation of the mutual distances of two vehicles from each other and the distances of the vehicles from the starting point A on the route as a function of the time of travel under the following conditions: - two veh
Phileas
According to a book written by Jules Verne in the 19th century, Phileas Fogg travelled around the world in 80 days. The Breitling Orbiter 3 balloon, which first circled the Earth without landing in 1999, was in flight for 19 days. The International Space
Wayne
Wayne can clear a plot of land in 1/3 hours, and Melvin can clear the same plot of land in 2/4 hours. What could possibly be the time for both Wayne and Melvin if they combine to clear the same plot of land?
An archer
An archer stands 60 meters (m) from a target. She launches an arrow that lands 3 centimeters (cm) from the bull's eye. The archer changes her position to 40 m from the target, and her next arrow lands 2 cm from the bull's eye. She changes her position to
Square point distance
I was given a square ABCD 4.2 cm. Find the set of all points that have a distance less than or equal to 2 cm from one of its vertices and lie inside this square. Indicate how much of the square this area occupies as a percentage.
Simultaneous start
A pedestrian and a cyclist set off simultaneously from two villages 24 km apart. The pedestrian walked at an average speed of 4 km/h and met the cyclist after ninety minutes of walking. What was the average speed of the cyclist?
Pool water flow
Five hundred liters of water will flow into the pool in 5 minutes, and 120 liters of water will flow out of it in 12 minutes. How many liters of water will be added in 1 hour?
Car motorcycle distance
A car travels 11,000 m in one minute. A motorcycle travels at a speed of 330 m in 11 seconds. Which of them will travel the greater distance in 1 hour of driving?
A chemist
A chemist recorded the change in temperature of a cooling liquid as −25.5° over a 1.5-minute period. The temperature fell at a constant rate. What was the rate of change in temperature? Enter your answer in the box. °F per minute
