The clark family went sailing, their boat averaged 6 kilometers per hour,
The Rourke family took their boat out for the same amount of time and their boat averaged 14 K perhour
the Rourke family traveled 20 kilometers farther than the Clark family,
How many hour did each family spend on their boat trip?
:
Let t = time they were both on the water
:
Write a dist equation; dist = speed * time
:
R's dist - C's dist = 20 km
14t - 6t = 20
8t = 20
t =
t = 2.5 hrs the time they were both on the water
:
:
See if that adds up
2.5(14) - 2.5(6) =
35 - 15 = 20 km difference
