A bus and a car departed from the station simultaneously in opposite directions, the speed

A bus and a car departed from the station simultaneously in opposite directions, the speed of the car is 70 km / h and the speed of the bus is 2 times less in how many hours the distance between them will be 525 km?

It is about the uniform movement of the bus and the car.

Formula for determining the speed of movement:

V = S / t;

V is the speed of uniform movement;

S – distance traveled;

t – travel time.

Find the bus speed:

Va. = 70 km / h / 2 = 35 km / h.

Moving in different directions, they are 525 km, they will pass with a general (total) speed:

Vtot. = 70 km / h + 35 km / h = 105 km / h.

Let’s find the travel time of the car and the bus:

t = S / V = 525 km / 105 km / h = 5 hours.

Answer: in 5 hours there will be 525 km between the bus and the car.
