Question

Jordan rides his bike 12 mi/hr faster than Nick walks. After Jordan rides his bike for 1 hour and 15 mins and Nick walks for 1 hour and 30 mins, the ratio of their distances is 5:3. Find both Jordan's and Nick's speed.

Answer 1

Jordan is riding at 24 mph and Nick is walking 12 mph.  After 1.25 hours Jordan travelled 30 miles and after 1.5 hours Nick travelled 18 miles.  Thus, 30/18 = 5/3
