20 km in half an hour = 2*20 = 40 km in an hour.
avg speed is = total distance divided by total time so its 160/2.5= 64miles/hr
To calculate average speed, you divide the total distance traveled by the total time taken. In this case, the total distance traveled is 164 kilometers, and the total time taken is 2.5 hours. Therefore, the average speed would be 164 km / 2.5 hours = 65.6 km/h.
40 km per hour. 20 x 2 because that is in a half hour.
Average speed is distance over time, so (25 + 35)/(.5 + 1.5) = 60/2 = 30 km/hr
It's 25 miles per half-hour, and it's also 50 miles per hour.
No. Light travels at about 875 thousand times the speed of sound.
No.

No, this does not mean that the 747 travels at the speed of sound. The 747's travel time is simply longer due to its slower speed compared to Concorde. Concorde's speed is faster than the speed of sound, allowing it to reach New York in half the time of a 747.
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.
