On flat terrain, a "normal" pace is about 2-4 km per hour, and "fast" pace is about 5 and 7 km per hour.
The average time would be about one hour
at around 7~8kmph i can do 4km in 35mins, that's including warming up to the 7kmph and a 5 minute cool down at the end
There really isn't an average time, as it's highly dependent on the fitness level and effort from the rider, and type of bike that's ridden. A reasonably fit rider on a nice bike should be able to do it in 4-6 minutes, but it could take up to 12 minutes for a more casual rider.
It depends how slow/fast you walk. It would approximately take 40-45 minutes at a regular walking pace.
15 to 20 minutes on a medium pace.
45 minutes to an hour
distance=speed x timeso speed = distance/time
The average during that period of time is 20 km/hour west .
around 110 km/h
To find the average speed, divide the distance travelled by the time. By this procedure, the average speed is 60 km/h.
This kind of question is tricky, because average velocity is not simply the average OF the velocities. The reason is you spend more time driving the slower part. The correct approach is to compute (average velocity) = (total distance) / (total time) Total distance = 232 + 232 km. Total time = (time going 46 km/h) + (time going 70 km/h) The above terms are found by computing distance/speed: at 46 km/h, it takes (232 km) / (46 km/h) = (232/46) hours etc. - you can finish the details.
45km/h or 27.961 miles per hour
The idea is to divide the distance by the time.
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)
time = distance/speed 150 m = 0.150 km 8/.150 = 53.3 minutes
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.
75 ÷ 30 = 2.5 hours
Answer: The person runs for 15 minutes = a quarter hour. So distance covered = a quarter of 6 km = 1.5 km. Answer: In general, you use the formula distance = speed x time. For this, you have to convert the units to compatible units (see the other answer, above). Also, please note that "6 km" is NOT a speed.
