Two trucks travelling to the store
truck a. is traveling 30 mph truck
truck b. is traveling 15 mph but leaves 20 seconds early
Who will arrive first?
-------------
In 20 sec the slower truck will go (20/3600)15 mph = 0.08333 miles
That leaves 0.25-0.08333 = 0.16667 miles to go.
The slower will cover that distance in 0.16667/15 = 0.0111 hrs
----
The faster truck covers the distance in 0.25/0.30 = 0.00833 hrs
-----
Ans: The faster truck will cover the distance before the slower truck arrives.
