A bus traveled on a level road for 6 hours at an average speed per hour taster than it traveled on a winding road. The time spent on the winding road was 5 hours. find the average speed on the level road if the entire trip was 472 miles

Solution

Dear Studennt Thank you for using Chegg !! Let the speed of bus on winding road be x miles/ hour Therefore as per question speed on levelroad = (x + 20) miles / hour Total Time spent on winding road = 5 hours Time spent on level road = 6 hours Distance covered on winding road = 5 (x) Distance covered on level road = 6 (x+ 20) Total Distance = 11x + 120 = 472 (Given) 11x = 352 x = 32 miles / hour Aaverage speed on level road = 32 + 20 = 52 miles / hour Solution
