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 a constant speed of 50 miles per hour? I need an equation and a thorough/ clear explanation on how to get answer.

distance from A to B = time x rate
= (6/60) (60) = 6 miles
So time to go at 50 mph , (Time = distance/rate)
= 6/50 hrs
= 6/50 * 60 minutes = 7.2 minutes
