Question

Chris and Pat go on a 30 km run. They both usually run at 10 km/h. If Chris runs at 1/2 his usual running speed, and Pat runs at 3/2 times her usual speed, how many more hours does it take Chris to complete the run than it takes Pat to complete the run?

A. 2 B.4 C.1 d.6

Answer 1

Answer: d.) 6
