# Two friends drove towards each other from different cities, the distance between which is 745 kilometers

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.
