For problem 1. 1 mile/gallon = 0.425 kilometer/liter 25 * 0.425 = 10.625 kilometers/liter The car can travel 10.626 kilometers on a liter of gas.
For problem 2. 1 milliliter = 0.000264 gallons 275 * 0.000264 = 0.0726 gallons 0.0726 gallons per minute 10 / 0.0726 = 137.74 It will take 137.74 minutes to pump 10 gallons Which is 2 hours, 17 minutes, 44 seconds
