Question 236033: Care one travels from point a to c (244 miles). Car two travels at 60 mph from point a to b(140 miles)and 50 mph from b to c (200 miles). If both cars arrive at point c at the same time, how fast did car one drive? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Care one travels from point a to c (244 miles).
Car two travels at 60 mph from point a to b(140 miles)and 50 mph from b to c (200 miles).
If both cars arrive at point c at the same time, how fast did car one drive?
:
Find the time required for car two to go a to b to c
Time = dist/speed
:
total time = time at 60mph + time at 50mph
t = +
t = 2.33 + 4
t = 6.33 hrs
:
Find the speed of car one to drive 244 mi in 6.33 hrs
s =
s = 38.5 mph speed of car one
