Roselyn is driving to visit her family, who live 150 kilometers away. Her average speed is 60 kilometers per hour. The car's tank has 20 liters of fuel at the beginning of the drive, and its fuel efficiency is 6 kilometers per liter. Fuel costs 0.60 dollars per liter.
How long can Roselyn drive before she runs out of fuel? $\square$ hours Show Calculator

Studdy Solution
Determine the time it takes to travel 120 kilometers at an average speed of 60 kilometers per hour.
$\text{Time} = \frac{\text{Total distance}}{\text{Speed}} = \frac{120 \text{ kilometers}}{60 \text{ km/hr}} = 2 \text{ hours}$
Hence, Roselyn can drive for 2 hours before she runs out of fuel.
