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

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

Answer 2

(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

`(6)/(6) L=(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

`(48)/(48)km=(6)/(48) L`

`1km=(6)/(48) L`

we can multiply both sides by 11

`11*1km=11*(6)/(48) L`

`11km=(11)/(8) L`..................Answer
