Question

. Two cars head towards each other from opposite ends of a highway 450 km long. The speed of the first car is 40 km/h. The speed of the second car is 50 km/h. The cars will meet in​

Answer 1

• The cars will meet in 5 hours

==========================

The two cars head towards each other. If the distance between them is 450 km they will make this distance together.

Add up the speeds of cars:

• s = 40 + 50 = 90 km/h

Find the time needed for the cars to meet:

• t = distance / speed
• t = 450 / 90
• t = 5 h
