A car uses 12.5 L of gasoline to travel a distance of 275 km. Convert this into units of miles per gallon (mi/gal).

The mileage of the car is 51.75 mil/gal.

Explanation:

Distance covered by the car = 275 km =

1 Mile = 1.609 kilometer

Volume of gasoline used by the car = 12.5 L =

1 gallon = 3.785 Liter

Mileage of the car :

=

The mileage of the car is 51.75 mil/gal.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
