Question

A vehicle uses 7 gallons of gasoline to travel 238 miles. The vehicle uses ganetine at a steady rate. Write a table of equivalent ratios.Then use the table to find the number of gallons of gasoline the vehicle uses to travel 714 miles.Complete the tableGallons Miles2371421

Answer 1

We will use the ratio way to complete the table

Because the rate is steady

Gallons Miles

1 x

7 238

To find x we will use the cross multiplication

$7\times x=1\times238$

So 7x = 238

to find x divide both sides by 7

x = 34

1 gallon cover 34 miles

Gallons Miles

2 x

7 238

we will do the same

$7\times x=2\times238$

7x = 476

Divide both sides by 7

x = 68

2 gallons cover 68 miles

Gallons Miles

3 x

7 238

7x = 714

Divide both sides by 7

x = 102

3 gallons cover 102 miles

Gallons Miles

14 x

7 238

7x = 3332

Divide both sides by 7

x = 476

14 gallons cover 476 miles

Gallons Miles

21 x

7 238

7x = 4998

Divide both sides by 7

x = 714

21 gallons cover 714 miles
