If it takes 6 minutes to travel from point A to point B at a constant speed of 60 miles per hour, how many minutes does it take to travel the same route from point A to point B at a constant speed of 50 miles per hour?

Math 
Reiny
let extra time for second trip be t hrs
(6/60)(60) = (6/60 + t)(50)
6 = 5 + 50t
50t = 1
t = 1/50 hours more
or 1.2 minutes
