You can put this solution on YOUR website! The speed of a laundry truck varies inversly with the time it takes to reach its destination. if the truck takes 3 hours to reach its destination traveling at a constant speed of 50 mph, how long will it take to reach the same location when it travels at a constant speed of 60 mph?
----------------
s = k/t
---
Solve for "k" using "the truck takes 3 hours to reach its destination traveling at a constant speed of 50 mph".
40 = k/3
k = 120
--------
Equation for the problem:
s = 120/t
----
How long will it take to reach the same location when it travels at a constant speed of 60 mph?
t = 120/s
---
t = 120/60
time = 2 hrs.
