Problema Solution
If shannon drives 40 miles per hour her trip lasts 30 minutes. If she drives 60 miles per hour how long will the same drive take her
Answer provided by our tutors
the average speed is inversely proportional with the time
t = the time it takes her to drive the distance with 60 mph
40*(30/60) = 60*t
by solving we find
t = 1/3 hr
click here to see the step by step solution of the equation
t = 60/3 min
t = 20 min
it will take her 20 min if she drives 60 mph.
