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 " :

Her car has fuel efficiency = 15 miles per gallon

Answer:

5 gallons.

Step-by-step explanation:

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.

$\text{Number of gallon used}=\dfrac{\text{Total distance travel}}{\text{Fuel efficiency}}$

$\text{Number of gallon used}=\dfrac{75}{15}$

$=5\text{ gallons}$

Hence, she needs 5 gallons.
