Clint and Jim rode their bicycles to Mill Park at an average of 8 mi/hr. It took then 1 hr longer to return home riding at an average of 7 mi/hr on a route that was 4 mi longer than their route. How long were they riding their bicycles? How man miles did they ride each way?

Total time for which they ride =

Number of miles they ride each way = 24 mi

Step-by-step explanation:

Average speed = 8 mi/hr

Let the Distance to Mill Park = mi

Let the time taken = hours

Formula:

..... (1)

Now, when average speed = 7 mi/hr

Time taken is 1 hour more, i.e. Time = hours

Distance traveled is 4 mi more, i.e. mi

Using the Formula:

From equation (1):

From equation (1):

Total time for which they ride =

Number of miles they ride each way = 24 mi
