Two cars simultaneously drove out of the city in different directions along a circular road. The speed of one car is 90 km / h, and the other is 20 m / s. What is the distance between cars along the road in 20 minutes if the length of the entire road is 100 km?

It is known that two cars left the city in different directions along a road in the form of a circle, the length of which is 100 km.

The speed of the first car is 90 km / h, and the second is 20 m / s.

It is required to calculate the distance between cars along the road in 20 minutes.

Let’s convert the speed of the second car into “km / h”.

20 m / s = 72000 m / s = 72 km / h.

Let’s find the speed of moving cars away.

90 + 72 = 162 km / h.

Find the distance traveled (20 min = 1/3 h).

162 * 1/3 = 54 km.

The distance along the road behind the cars will be 54 km, and 46 km in front.
