1.5 km is a distance, not a speed.
distance traveled=60 km.time =45 minutes=45/60 hrs=0.75 hrsthen speed =distance traveled/total time=60/ 0.75 km/hr=80 km/hr
An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is? 80 km in 10 minutes = 8 km/min 100km in 20 minutes = 5 km/min Average speed = total distance traveled ÷ total time Average speed = 180 km ÷ 30 min = 6 km/minute Notice the average speed is closer to 5 km/min, because the plane spends twice as much time traveling at the slower speed.
Wiki will not help you cheat. Time to get to work.
avg. speed = distance traveled / timeso, 100 km / 1.25 hours = 80 km/hr
speed = distance / time = 80 km / 0.75 hr = 80 km / ¾ hr = 80 × 4/3 km/h = 106 2/3 km/h ≈ 107 km/h
The speed is the distance traveled divided by the time it takes to travel that distance. In this case we with divide 8 kilometers by 10 minutes to get 0.8 km/minute. One hour is sixty minutes, so this works out to 48 km/hour.
Moving 12 km in 40 minutesMoving 6 km in 15 minutesMoving 10 km in 20 minutesMoving 18 km in 30 minutesThat’s the answer!
21 km/h
90kms
The average speed of the car = 300 [km] / 5.5 [h] = 54.55 [km/h]. ==========================
The answer is average speed.It's average speed because say for example you know your car is traveling 30 km in 20 minutes, you'd have to divide the total distance traveled by the total time.
