Answer: 0.1714 miles / hour
Step-by-step explanation:
Given the following :
Distance to the store = 3 miles
Time taken to get to store = 12 hours
Time taken to return = 23 hours
The average rate of speed for the trip =?
Average Speed = total distance traveled / total time taken
Total distance traveled = 2 × 3 miles = 6 miles
Total time taken = 12 + 23 = 35 hours
Average speed = 6 miles / 35 hours
Average speed = 0.1714 miles / hour
Answer:
0.176 $
Step-by-step explanation:
Write a proportion.
37 dollars is to 210 square inches as x dollars is to 1 square inch.
37 $ / 210 in² = x / 1 in²
x ≈ 0.176 $
X + y = 1.....multiply by -1
4x + y = -23
---------------
-x - y = -1 (result of multiplying by -1)
4x + y = -23
---------------add
3x = - 24
x = -24/3
x = -8 <====
x + y = 1
-8 + y = 1
y = 1 + 8
y = 9 <====
