## Homework Statement

to qualify for a race a car must achieve an average speed of 254 km/hr on a track 1600 meters long. if a car covers half the track with an average speed of 227.5 km/hr what minimum average speed must it have the second half to qualify?

## Homework Equations

speed=distance/time

## The Attempt at a Solution

my teacher told us to find the time it took for the first half and i did that by converting 227.5km/hr and getting 63.19m/s=800/t and got 12.6 seconds for the first half. he told us we could use this to solve the problem but im really confused on how to do that.
