Question 1096125: A bus traveled on a level Road for 3 hours at an average speed 20 miles per hour faster than it traveled on the 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 jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the speed of the bus on the winding road. Then, its' speed on a level road would be n+20. So:
3(n+20)+4n=305
7n=245
n=35
The average speed on the level road was n+20, or 55 mph. ☺☺☺☺
