<PRE><B>Question 637717</B>
A car needs 1 minute 30 secondes to travel a distance of 1 mile.
At this rate how many miles will the car travel in 1 hour?
-----
1 min 30 seconds = 90 seconds = (90/3600) hrs
-------------------------
rate = distance/time
rate = (1/(90/3600))mph = 3600/90 = 40 mph
======================
Ans: 40 miles
