Question

Two cars leave towns 300 kilometers apart at the same time and travel toward each other. One car's rate is 14 kilometers per hour less than the other's. If they meet in 2 hours, what is the rate of the slower car?

Answer 1

Say the first car speed as r

Second car speed will be r-14

Since rate times time equal distance, we have

r + (r -14)2 = 300

2r -14 = 300/2

2r = 150+14

r = 164/2 = 82

Speed of slower car 82-14 = 68 km/hr
