Nitella [24]

Answer:

5

10

4

7

           = 5

5² - 15 = 25 - 15

          = 10

5(5) - 21 = 25 - 21

5 + 10 - 8 = 15 - 8

               = 7

A truck uses 1 tablespoon of gasoline to drive 125 yards. How many miles can the vehicle travel per gallon?
Alborosie

Answer:

18.18 miles.

Step-by-step explanation:

A truck uses 1 tablespoon of gasoline to drive 125 yards.

Now, 1 gallon of gasoline contains 256 tablespoons of gasoline.

So, the truck uses 1 gallon i.e. 256 tablespoons of gasoline to drive (256 × 125) = 32000 yards.

Now, 1-mile distance contains 1760 yards.

Therefore, the truck uses 1 gallon of gasoline to drive \frac{32000}{1760} = 18.18 miles. (Answer)
