# Two cars start at the same time from opposite ends of a highway that is 45 miles long.

Two cars start at the same time from opposite ends of a highway that is 45 miles long. One car is riding at 14 mph and the second car is riding at 16 mph. How long after they begin will they meet?

## Answer/Solution

1.5

### Steps/Work

As cars are moving in opposite directions their speeds will be added. So their relative speeds: 16+14 = 30 mph

Total distance to be covered = 45 miles.

Time taken would be: 45 miles/30 mph = 1.5 hours

E is the answer.

Total distance to be covered = 45 miles.

Time taken would be: 45 miles/30 mph = 1.5 hours

E is the answer.
