Two friends drove towards each other from different cities, the distance between which is 745 kilometers. The first traveled by bus at a speed of 65.7 km / h. The second one – by car, the speed of which is 85.9 km / h. What is the distance between friends in 3 hours if friends left at the same time?

First, you need to add together the speed of the bus with the speed of the car – then we can calculate the speed of convergence, that is, the distance at which two others will approach each other in one hour.

1) 65.7 km / h + 85.9 km / h = 151.6 km / h – approach speed.

Now let’s calculate the distance that a bus and a car will approach each other in 3 hours:

2) 151.6 km / h * 3 h = 454.8 km.

Next, let’s find out the distance that will separate friends in three hours of travel:

3) 745 km – 454.8 km = 290.2 km.
