- A river
A river flows at a speed of 5 km/h. A man can swim at 20 km/h in still water. The man starts swimming from A to B, a distance of 30 km. After reaching B, the man turns back and stops at point A. Find the total time for the round trip. - Acceleration - gravity
What is the gravitational acceleration if a body with a mass of 5.8 kg fell from 68 metres and hit the ground at a speed of 60 km/h? - Two trains 12
Two trains 128 m and 132 m long are running towards each other on parallel lines at 42 km/h and 30 km/h respectively. In what time will they clear of each other from the moment they meet? - Peleton
In a cycling race, the peloton travels at an average speed of 36 km/h. One competitor stopped for 5 minutes to repair a puncture. By how many kilometres per hour did his speed exceed the speed of the peloton when he caught up with it in 20 minutes? How lo - Diesel tank filling
The diesel tank has a volume of 19.6 hl. The inflow oven, which flows 17.5 l per minute, was opened for 1.5 hours. How long does the inlet pipe need to be opened for the tank to be completely filled? - Car acceleration distance
How far must a car travel to reach a speed of 72 km per hour if it starts from rest in a uniformly accelerated motion with an acceleration of 0.2 meters per second²? - Hours minutes fraction
How many minutes are there in 5/6 hours? - Crane hook distance
What distance did the crane hook travel in 1 min at a constant speed of 15 cm/s? - In the desert
A man wondering in the desert walks 5.7 miles in the direction S 26° W. He then turns 90° and walks 9 miles in the direction N 49° W. At that time, how far is he from his starting point, and what is his bearing from his starting point? - Bucket tap filling
A bucket is filled by one tap in 4 minutes and by another tap in 3 minutes. How many minutes will it take to fill 5 buckets if both taps run simultaneously? - Storm distance sound
The sound travels at a speed of 1 km in 3 seconds. If the thunder is heard 12 seconds after the lightning, what distance is the storm? - Runner acceleration speed
The runner reaches a speed of 30 km/h after 3 seconds from the start. Determine its acceleration. - Speed of light
Calculate the speed of light if a distance of 3000 km travels in 0.01 s. - When Emily
When Emily arrived home from school, she spent 8 minutes eating a snack. Then, she spent 15 minutes playing with her dog and 32 minutes doing her chores. Finally, Emily spent 45 minutes finishing her homework. How long had Emily been home when she finishe - Wave travel time
A plane wave has an amplitude u0 = 40 cm and a frequency f = 10 Hz. The speed of wave propagation through the medium is v = 40 cm/s. At a distance x = 10 cm from the starting point, the wave has an instantaneous deflection u = 15 cm. How long does it take
