Distance problem.

Question

Hillary and Zoe are 105 miles apart, traveling towards each other. If Zoe travels 14 mph and Hillary travels 7 mph how long until they meet

Answer 1

Nate, this is a simple speed problem.

The equation we need is: S = D/T where S = speed (mph), D = distance traveled (miles), and T = time (hours)

Also, we can simplify by assuming Hillary isn't moving and Zoe is traveling at 14 + 7 = 21 mph. This give the same answer.

Rewriting the above equation: T = D/S

Therefore, time to meet = 105 / 21 = 5 hours.
