Question 1164423: Thaddeus and Ian start at the same location and drive in opposite directions, but leave at different times. When they are 635 miles apart, their combined travel time is 12 hours. If Thaddeus drives at a rate of 50 miles per hour and Ian drives at a rate of 55 miles per hour, how long had each been driving? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! T drove x hours
I drove 12-x hours
50x+55(12-x)=635
-5x+660=635
x=5 hours
Thaddeus drove 5 hours @50 mph or 250 miles
Ian drove 7 hours @ 55 mph or 385 miles
