dsp73

Answer:

9 gallon of gas

Step-by-step explanation:

When distance covered is 378 miles, they have used 14 gallons of gas

We need to find how much gas will they need to finish the trip if 243 miles left to drive on the trip.

378 miles = 14 gallons of gas

For 1 mile,

1 gallon of gas is used for $\dfrac{14}{378}\ \text{gallon of gas is used}$

For 243 miles,

$= \dfrac{14}{378}\times 243\ \text{miles}\\\\=9\ \text{gallon of gas is used}$

Hence, for 243 miles 9 gallon of gas is used.
