Given:

A car uses petrol at the rate of 1 gallon for every 30 miles.

To Find:

The number of gallons of petrol required to travel 177 miles.

Solution:

We are required to find the number of gallons of petrol required to travel 177 miles.

The number of gallons of petrol is directly proportional to the distance traveled in miles.

The number of gallons of petrol ∝ distance traveled in miles.

1 gallon of petrol ∝ 30 miles   ---------(1)

? gallon of petrol ∝ 177 miles

Let 'x' be the number of gallons of petrol required to travel 177 miles.

'x' gallon of petrol ∝ 177 miles  ------(2)

On dividing equation(2) by equation(1)

x/1 = 177/30

x = 5.9

Therefore, The number of gallons of petrol required to travel 177 miles is 5.9.
