Question 873600
A passenger train and a freight train which are 300 miles apart travel
toward each other at rates 60 mph and 30 mph. In how many hours will they meet each other
.
Let x = time (hours) when they'll meet
then
60x + 30x = 300
90x = 300
x = 300/90
x = 3.333
or
x = 3 hours and 20 minutes
