Question

A) 4.5 gallons
B) 6.5 gallons
C) 5 gallons
D) 7.5 gallons

Answer 1

To travel 105 miles, Ar would need approximately 4.5 gallons of gas.

Step-by-step explanation:

To find out how much gas Ar would need to travel 105 miles, we can use the concept of ratios. Since we know that Ar needs 3 gallons of gas to travel 70 miles, we can set up the following proportion: 3 gallons / 70 miles = x gallons / 105 miles. To solve for x, we can cross-multiply and then divide. Cross-multiplying gives us 70x = 3 * 105. Dividing both sides by 70, we find that x = 4.5 gallons.
