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
( x³ + 3 x² + 16 x + 48 ) : ( x + 3 ) = x² + 16
- x³ - 3 x²
-----------------------------
16 x + 48
- 16 x - 48
---------------------
r = 0
Answer: x² + 16
