Roselyn wants to drive her car at a speed of 60 miles per hour for 1.25 hours her car has fuel efficiency of 15 miles per gallon how many gallons of fuel does roselyn need for her journey
5
1.25 hours = 75 miles = 1/4 of 60 is 15 (of the 1.25)
75/15 (miles per gallon)
Answer: Hence, there is 5 gallons of fuel Roselyn needed for her journey.
Step-by-step explanation:
Since we have given that
Speed at which Roselyn wants to drive her car = 60 miles per hour
Time taken by her car = 1.5 hours
As we know the formula for "Distance-Speed " :
\(Distance=Speed\times Time\\\\Distance=60\times 1.25\\\\Distance=75\ miles\)
Her car has fuel efficiency = 15 miles per gallon
Number of gallons of fuel is given by
\(\frac{75}{15}\\\\=5\ gallons\)
Hence, there is 5 gallons of fuel Roselyn needed for her journey.
