If a car can drive 62 miles on 3 gallons of gas, how many gallons of gas will it use to travel 231 miles?
aksik [14]

Answer:

11 gallons of gas is needed to travel 231 miles.

Step-by-step explanation:

We can set up a proportion for this problem.

<em>For every 62 miles, you use 3 gallons of gas. </em>

\frac{62}{3}*\frac{231}{?}

Now, let's cross multiply.

\frac{693}{62} ≈ 11

So, you will need about 11 gallons of gas to travel 231 miles.

Virty [35]
Law of sines can be used to solve this problem:

(note - let x represent the missing side length.)

1. set up proportion.
sin 90°/25 = sin 55<span>°/x

2. solve.
(x) sin 90</span>° = (25) sin 55<span>°

(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
