Question

Two runners live 33 miles apart. jim runs 8 miles per hour, and joan runs 6 miles per hour. if joan starts running toward jim's house and jim starts running toward joan's house 2 hours later, how long will jim have been running when they meet?

Answer 1

Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5

3.5 hrs is the hours that Jim have been running until he met Joan.
