Question

If an automobile gets 24.5 miles to the gallon and the cost of gasoline is $2.75 a gallon, how much will it cost to drive 975 km? (note: monetary values are often reported to the nearest cent.)

Answer 1

In order to know how much will it cost to drive 975 km, we need first to know how many gallons it would take to drive 975 km. First, we need to convert kilometers to miles. 975 km would be equal to 605.84 miles (1 km = 0.62 miles). Since one gallon can be consumed up to 24.5 miles, we need to divide 605.84 miles by 24.5 miles to know how many gallons will be consumed travelling such distance. Dividing the two numbers, we can get 24.73 gallons. We know that one-gallon costs $2.75. Therefore, it would cost $68.01 ($2.75 x 24.73 gallons) to drive 975 kilometers.
