Problema Solution
The time (t) traveled by Delmar in a car varies inversely as rate (r). If Delmar drives at a
speed of 60 mph in 12 hours, what will be the time to travel if he drives at 75 mph?
Answer provided by our tutors
let 'x' represent the time travelled at 75 mph
60*12 = 75*x
solving for 'x' we have x=48/5 = 9.6
the time to travel will be 9.6 hours
