Answer:
15 miles
Explanation:
Speed of John biking = 10 miles per hour
Time taken by John to travel the route = 1.5 hours
We know that
distance = speed * time
now that we know time and speed for John
we can distance by using the above formula
distance = 10 miles per hour* 1.5 hour = 15 Miles
Thus, the route was 15 miles long.
