Two cyclist start at the same time from opposite ends of a course that is 45 miles long. One cyclist is riding at 14 miles per hour and the second cyclist is riding at 16 miles per hour. How long after they begin will they meet?

Applying the "distance formula" of d=rt
.
Let x = time (hours) they will meet
then
14x + 16x = 45
30x = 45
x = 45/30
x = 1.5 hours
or
x = 1 hour and 30 minutes
