The total amount spent on fuel on this trip is $14.21.
First find out the distance travelled:
= Speed x Time
= 70 x 1⁴⁵/₆₀
= 122.5 miles
The car takes a gallon of fuel to travel 25 miles and 122.5 miles were traveled. The total amount of fuel used was therefore:
= 122.5 / 25
= 4.9 gallons of fuel
If each gallon costs $2.90, the total amount spent is:
= 4.9 * 2.90
= $14.21
The total amount spent on fuel on this trip is therefore $14.21.
