Question

Amelia used 6 liters of gasoline to drive 48 kilometers.How many kilometers did Amelia drive per liter?At that rate, how many liters does it take to drive
11 kilometer?

Answer 1

(a)

We are given

Amelia used 6 liters of gasoline to drive 48 kilometers

so, we have

6 litres = 48 kilometers

we can divide both sides by 6

$\frac{6}{6} L=\frac{48}{6}km$

$1 L=8km$

so, we get

$rate =8km/L$

(b)

now, we have to find number of litres after 11 km

6 litres = 48 kilometers

we can also write it as

48 kilometers=6 litres

we can divide both sides by 48

$\frac{48}{48}km=\frac{6}{48} L$

$1km=\frac{6}{48} L$

we can multiply both sides by 11

$11*1km=11*\frac{6}{48} L$

$11km=\frac{11}{8} L$..................Answer

Answer 2

8 kilometers per liter and it would take 0.125 liters of gasoline to drive 1 kilometer
