Two trains left the two cities at the same time towards each other. The first went at a speed of 65 km / h. this is 7 km / h more than the second. in how many hours will they meet if the distance between them is 246 km.
1) Let’s find out at what speed the second car was moving, if it is known that it is 7 km / h less than the first car.
65 – 7 = 58 km / h.
2) Let’s find out what distance two cars traveled in 1 hour, if it is known that the speed of the first car is 65 km / h, and the second one is 58 km / h.
65 + 58 = 123 km.
3) Find out how long it takes two cars to cover a distance of 246 km, if it is known that in 1 hour they cover 123 km.
246/123 = 2 hours.
