the amountof time for a trp varies inversely as the speed traveled.
t = k/s
-------------------
a car reached its destination in 9 hours traveling at 60 mph .
Find "k" by substituting these numbers:
9 = k/60
k = 540
Equation: t = 540/s
--------------------------------
what must its speed be to get there in only 8 hours?
8 = 540/s
s = 540/8 = 135/2= 67.5 mph
