Question 93707: A cross country skier starts at a certain point and travels at a constant speed of 4 miles per hour. A snowmobile starts at the same point 45 minutes later, traveling at a constant speed and follows the skier's tracks. If the snowmobile catches up to the skier in 10 minutes, what is the speed of the snowmobile?

You can put this solution on YOUR website! A cross country skier starts at a certain point and travels at a constant speed of 4 miles per hour.
A snowmobile starts at the same point 45 minutes later, traveling at a constant speed and follows the skier's tracks.
If the snowmobile catches up to the skier in 10 minutes, what is the speed of the snowmobile?
------------------
Skier DATA:
Rate=4 mph ;time=[(3/4)+(1/6)]=(22/24)hrs;distance=rt = 22/6 miles
-------------------
Snowmobile DATA;
Rate = x mph;time=(1/6)hr; distance = x/6 miles
------------------------
EQUATION:
skier distance = snowmobile distance
22/6 = x/6
x = 22 mph (snowmobile speed)
==================
