avg. speed = distance traveled / timeso, 100 km / 1.25 hours = 80 km/hr

The average speed of the car = 300 [km] / 5.5 [h] = 54.55 [km/h]. ==========================

The average speed would be 30 km/h Speed is measured in length per time (for example km/h), so to calculate the average speed you divide 75 km by 2.5 hours. 75km/2.5hours - which would be 75/2.5 km/h = 30 km/h.

21 km/h

30 kph

By unit of length and distance and conversion ,we can say that speed=distance/time time=1250/65=19.23 hours

40

Average speed is the total distance traveled divided by the time taken.Average speed = total distance traveled/time taken = 90 km/3 h = 30kph

Average Speed is the distance traveled divided by the time it took to travel that distance.In this case, the distance traveled is 240 km, and the time is 3hrs.You do the calculation. (your answer will have the unit km/hr)

maybe, you should get off wiki answers, and figure it out. lets see, you need to divide it down to km/pH. 80 kilometers = 2 hours, 40 kilometers in 1 hour. average speed? 40 km. that's saying they don't stop anywhere.

5k/ph depending if your going down a hill or up 1 ======================================== Let's put a somewhat finer point on it: First, you traveled 80 km/hr for 3 hours, covering (80 x 3) = 240 km. Then, you traveled 60 km/hr for 4 hours, covering (60 x 4) = another 240 km. At the end of that time, you had traveled for (3 + 4) = 7 hours and covered (240 + 240) = 480 km. Your average speed is (480 / 7) = 68.57 km/hr(rounded)
