Question 93503: I hope this is the last question I have on this homework assignment, could someone please help?
On a 195mi trip, a car traveled at an average speed of 45mph and then reduced its speed to an average of 30mph for the remainder of the trip. The trip took a total of 5 hours. How long did the car travel at each speed? Thanks for any help you are able to give.
Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
195=45x+35(5-x)
195=45x+175-35x
10x=195-175
10x=20
x=20/10
x=2 hours @ 45 mph.
5-2=3 hour for 35 mph.
proof
195=45*2+35*3
195=90+105
195=195
