Devon set out to bicycle from Exeter to the beach, a distance for 10 miles. After going a short while at 15 miles per hour, the bike developed a flat tire, and the trip had to be given up. The walk back to Exeter was made at a deected 3 miles per hour. The whole epsiode took 48 minutes. How many miles from Exeter did the flat occur?

Distance between Exeter and the point where flat tire occurred was 1.875 miles.

Step-by-step explanation:

Let the distance of Exeter and the point where bike developed the flat tire was = x miles

Then time taken to reach that point with speed 15 mi per hour =

= hours

Devon comes back with a speed of 3 miles per hour then time taken to come back = hours

Total time for the entire episode = 48 minutes or hours

Therefore,

x =

x = miles

x = 1.875 miles

Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.
