A motorist traveled 250 miles on 11 gallons of gas. With the same vehicle, about how far could he go on 16 gallons of gas? A) 17
Andrei [34K]
ANSWER

363.6 \: miles
EXPLANATION

We were told that the motorist travelled 250 miles on 11 gallons of gas. This implies that,

250 \: miles \equiv11 \: gallons

Now we want to find how far he could go on 16 gallons.

x \: miles \equiv16 \: gallons


All other things being equal, the motorist should cover more than 250 miles with 16 gallons of gas.

Recall that: If more, less divides.

This implies that,

x =  \frac{250 \times 16}{11}




x =  \frac{4000}{11}   = 363.6 \: miles


Therefore the correct answer is C.
