Question

2.1.43 A particular hybrid car travels approximately 235 mi on 5 gal of gas. Find the amount of gas required for a 705-mi trip. The car needs allons of gas for a 705-mi trip (Type an integer or a decimal.)

Answer 1

Answer: 15 gallons of gas is required for a 705 miles trip.

Explanation:

Since we have given that

Number of miles in a trip = 235 miles

Number of gallon of gas is needed = 5

We need to find the amount of gas required for 750 miles trip.

Since there is direct variation, as for increase in number of miles, amount of gas must be increased.

According to question, it becomes,

`(235)/(5)=\frac{705}x}\\\\47=(705)/(x)\\\\47x=705\\\\x=(705)/(47)\\\\x=15\ gallons`

Hence, 15 gallons of gas is required for a 705 miles trip.
