Question

a vehicle uses 1 tablespoon of gasoline to drive 125 yards. how many miles can the vehicle travel per gallon? round the answer to the nearest mile. (256 tablespoon= 1 gallon.)

Answer 1

how many yards in a mile?

Answer 2

1760

Answer 3

18.18 miles

Answer 4

use conversion factors such that the units "cancel out" in a numerator and denominator and the only remaining are miles/gallon

\[\frac{ 125 yards }{ 1 tbsp } \times \frac{ 1760 miles }{ 1 yard } \times \frac{ 256 tbsp }{ 1 gallon} = \frac{X miles }{ 1 gallon }\]
