A car uses 3t gallons of gasoline to travel 5 miles.
Nadusha1986 [10]

Answer: a) \frac{24}{5}t gallons are needed to travel 8 miles

b) Town X and town Y are 15 miles apart.

Step-by-step explanation:

Given : Gasoline used to travel 5 miles = 3t gallons

a) To find: Gasoline used to travel 8 miles = ?

Using unitary method:

If Gasoline used to travel 5 miles = 3t gallons

Thus Gasoline used to travel 8 miles = \frac{3t}{5}\times 8=\frac{24}{5}t gallons

\frac{24}{5}t gallons are needed to travel 8 miles

b) when 3t gallons of gasoline are used , distance covered = 5 miles

Thus when 9t gallons of gasoline are used , distance covered = \frac{5}{3t}\times 9t=15 miles

Thus town X and town Y are 15 miles apart.
