20 km in half an hour = 2*20 = 40 km in an hour.
17.14286 km. hr. is the avg. speed
5530/790=7 hours
15 km/h because you divide distance by time ;) When converted to other units, it's equivalent to: -- 250 meters per minute -- 41/6 meters per second
time =distance divided by speed time = 4700/790 = 5.95 hours = 5 hours 57 minutes
She travelled 140 + 300 ie 440 km in 7 hours. Her average speed was 440/7 or just a hair under 63 kph.
In kph it would be 40 kph.
25 kilometers
50kph
Average Speed
17.14286 km. hr. is the avg. speed
Average speed = distance / timedistance = 10 kmtime = 1.5 hoursAverage speed = 10 km / 1.5 hours = 6.67 km/hoursor1 mile = 1.60934 km6.67 km/hr = 4.14 miles/hrBecause we do not know if the speed of the bicyclist was constant or not, we can only give the average speed of this cyclist.
Anything that goes 543 kilometers in 6 hours is averaging 90.5 kilometers per hour
His average speed was 55 kilometers per hour.
If what you want is the total distance traveled, you need to multiply the average speed by the time.Please note that "59 kilometers" is not a speed; perhaps you mean "59 kilometers per hour". If, on the other hand, "59 kilometers" is the TOTAL DISTANCE, and you want the average speed, you need to divide the total distance by the time.
A car that travels 1000 kilometers in 5 hrs, averages 200km/h.
Average speed is the total distance traveled divided by the time taken.Average speed = total distance traveled/time taken = 90 km/3 h = 30kph
Distance = Rate * TimeAlgebraically manipulated,Time = Distance/RateTime = 4700 kilometers/190 kilometers per hour= 24.7 hours=============================
