Asked by Roberto Lewis

You pass a road sign saying "New York 125 km." If you drive at a constant speed of 65 mi/h, how long should it take you to reach New York? (Round to the nearest minute.) If your car gets 28 miles to the gallon, how many liters of gasoline are necessary to travel 125 km?

125* (0.622/1)= 77.75
77.75* (1/65)= 1.19615= 1.2 hours
77.75*(1/28)= 2.77679
2.77679*(3.77/1)=10.4685= 10.5 L of gas

This is chemistry??? Looks like math to me.
125 km = 77.7 miles. Check that !
d = r*t
77.7 = 65*t. Solve for t in hours.
28 mi/gallon x ? gallons = 77.7 miles
? gallons = 77.7/28 = 2.8 gallons
2.8 gallons x 3.78 L/gallon = ? L

^^^^ 2.8 gallons x 3.78 L/gallon = 10.584 L
