two trucks going to the store which is a quarter of a mile away one truck is traveling 30 miles per hour the other is traveling 15 miles per hour but gets a 20 second head start who will get there first
--------------------------
Faster truck DATA:
dist = 0.25 mile ; rate = 30 mph ; time = 0.25/30 = 0.00833 hrs
= 30 seconds
---------------
Slower truck DATA:
dist = 0.25 mile ; rate = 15 mph ; time = 0.25/15 hrs = 60 seconds
-----
The slower truck gets a 20 sec lead so his time is 40 sec.
---
Ans:: The faster truck beats the slower.
