You ride your bike at an average of 12 miles per hour on the way to school, and at an average of 15 miles per hour on the way ho
me. The total ride time is 22 minutes. How far away is school? Round your answer to the nearest hundredth of a mile
1 answer:
Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles
