You pass a road sign saying "New York 112km." If you drive at a constant speed of 65 mi/h, how long does it take you to reach New York? If your car gets 28 miles to the gallon, how many litters of gasoline are necessary to travel 112 km?How many litters of gasoline are necessary to travel 112km?First, we need to convert everything to the same unit. I will change everything into miles and liters.
112km=69.5935 mi
1 gallon= 3.79 liters
(1) If you drive at a constant speed of 65 mi/h, how long does it take you to reach New York?
distance/speed= time
69.5935mi/ 65mi/h= 1.07h
(2)If your car gets 28 miles to the gallon, how many litters of gasoline are necessary to travel 112 km?
This means 3.79 liters will be needed for 28 miles.
We know have 112km(69.5935 mi),
69.5935miles x 3.79 liters/ 28 miles= 9.42 liters
hope that answers your question!!
