Tina and Jim live 5 miles apart from each other. Tina ran from her house to Jim's house at a rate of 10 miles per hour. Jim ran from his house to Tina's house at a rate of 8 miles per hour. How far had Jim run by the time he crossed paths with Tina?

Answer 1

they are approaching at the rate of 18 mi/hr
They only had to cover 5 miles, so that took 5/18 hours

In that time, Jim ran 10 * 5/18 = 25/9 miles

Answer 2

if what you say about their approaching rate is true, jim ran 8 * 5/18 = 20/9 miles
