For 15.0 minutes, Gabby drove her tractor across a field at a constant velocity. During the
drive, she startled a crow, which flew away at 220 meters per minute. If her tractor traveled
246 meters during this time, what was the tractor's velocity?
Write your answer to the tenths place.

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

i did it myself and i got 4.2 (b) hope its right
