Asked by Chen

You pass a road sign saying "New York 112 km." If you drive at a constant speed of 65 mi/h, how long should it take you to reach New York? If your car gets 28 miles to the gallon, how many liters of gasoline are necessary to travel 112 km?

This is an exercise in conversions.
a. Convert 112 km to miles, then
distance = rate x time. Substitute distance in miles, rate = 65 mph, solve for time in hours.

b.
Convert 28 miles to km and gallon to liters.
Then km/L x #L = 112 km. Solve for #L.
