Roselyn wants to drive her car at a speed of 60 mph

Speed of car, S = 60 mph

She drives for 1.25 hours.

Time travel, t = 1.25 hours

Total distance travel = s × t

                                  = 60 × 1.25

                                  = 75 miles

The fuel efficiency of car is 15 miles per gallon.

Hence, she needs 5 gallons.
