- Bus speed calculation
A bus driver on a route between two neighboring villages travels at an average speed of 70 kilometers per hour and takes 1/2 hour. At what speed must he goes if he is 10 minutes late and wants to get to the neighboring village on time? - Car cyclist pursuit
Behind a cyclist traveling at an average speed of 20 km/h, he left the same place 2 hours later than a passenger car at an average speed of 60 km/h. How long and at what distance will the passenger car catch up with the cyclists? - Voltmeter range
We have a voltmeter that, in its original setting, measures up to 10 V. Calculate the resistance of the series resistor (multiplier) needed to extend the range to 50 V. The voltmeter's internal resistance is 2 kΩ/V. - Cyclist pursuit
The pedestrian walks at a speed of 4.3 km/h. In 1 hour and 10 minutes, a cyclist followed him at an average 18 km/h speed. How many minutes will a cyclist reach a pedestrian, and how many kilometers will he travel? - Polder filling
The polder has two tributaries. A larger inflow will fill an empty polder in 12 hours. The polder is already a quarter full. If we open both tributaries, the polder will be filled in 6 hours. How long would it take for a smaller inflow to fill an empty po - Two trains
From station A, the freight train traveled at a speed of 40 km/h in 9 hours. When he drove 15 km, the fast train started from station A in the same direction at 70 km/h. When will the freight train catch up? - Tea Blend Mixture

What is the weight of an empty water tank, and how many kilograms of water is in it? If the total weight a) 192 kg, would it drop to 132 kg after a third of the water weight is drained? b) 107 kg would increase to 132 kg after adding a quarter of the curr - Average speed
When the bus stops at a bus stop, the average speed is 45 km/h. It would drive at 54 km/h if it did not stop. How many minutes of every hour does it spend at stops? - Plane and helicopter
From two airports, a plane and a helicopter took off at the same time. The helicopter was flying to the airport from which the plane took off, the plane to the airport from which the helicopter took off. When they passed each other, the helicopter had flo - A stone
There is a stone weighing 60 kg on the billet. The distance from the support point to the stone is 20 cm. The length of the billet is 1 m. Determine the force exerted by the hand at the end of the billet. - Braking acceleration
At the start of braking, the car had a speed of 72 km h at -1. It stopped on a track of 50 m. What was the acceleration, and how long did the braking last? - The car
A car travelled the distance from A to B in four hours. If the average speed is increased by 17 km/h, the car covers the same distance one hour sooner. Determine the initial speed of the car and the distance between A and B. - Cyclist vs car
The cyclist rode out of the city at 18 km/h. One hour 30 minutes behind him started the car and caught up with the cyclist in 50 minutes. How fast was driving the car? Where (what kilometer) from the city car overtook a cyclist? - Pool filling time
