A car travels at 60 miles per hour and gets 14 kilometers per liter of gasoline.
Part A
How many gallons of gasoline are needed for a 2.1-hour trip?
Express your answer to two significant figures and include the appropriate units.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
