Question 927007: Two cousins are traveling to their grandmother's house for Thanksgiving. They decide to meet up to ride together. If they live 270 miles apart and one car is traveling at 80 miles per hour and the other car at 70 miles per hour, how many total minutes will it take before the two cousins meet up?

You can put this solution on YOUR website! relative speed of the cousins = 80 + 70 = 150 mph

s = d/t
t = d/s

t = 270/150
t = 1.8 hours * 60 min/hr
t = 108 minutes
