The average speed of the car for the whole journey would be 25 kilometers per hour.
202.5 mph
This question is invalid. The speed needs to be a rate, not a measurement.
53
300 kph.
average speed = S1+S2/2 here s1 = 40kmph s2 = 60kmph Average speed = 40+60/2 100/2 = 50 kmph
Average speed is distance over time, so (25 + 35)/(.5 + 1.5) = 60/2 = 30 km/hr
They need not.
65.5 mph Assuming that home is in Smallville. The average is (76+55)/2 = 65.5 MPh
40 MPH is the average speed
Its average orbital speed is 9.69km/s.
s=vt t=s/v ATQ 50=150/t so t=3 and 30=150/t t=5 avg speed=total distance / total time so 150+150/5+3 =300/8=37.5=avg speed
what is the average speed of a soccer ball that travels 34 m in 2 s
