Question 29372: Hello, I have an alegebra problem. The answer I came up with is 12.70 average speed, but I don't think I am correct. Could you please help me?
A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 4 hours. Find the average speed on the level road if the entire trip was 305 miles
Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
Level road speed = x+20
Winding road speed = x
Total milies driven = 305
Equation:

3(x+20)+4(x)=305
3x+60+4x=305
7x=245
x=35

35+20=55

Hence, on the level road the bus at 55mph and on the winding road the bus traveld at 35mph.
