On flat terrain, a "normal" pace is about 2-4 km per hour, and "fast" pace is about 5 and 7 km per hour.
Previous Answer:
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
The average time for a person to run 3 km can vary depending on their fitness level and running pace. Typically, for a healthy individual, it may take around 15-25 minutes to run 3 km.
distance=speed x timeso speed = distance/time
The time it takes a beginner to cycle 20 km can vary based on factors like fitness level, terrain, and cycling experience. On average, a beginner might cycle at a speed of 12-15 km/h, meaning it could take roughly 1.5 to 2 hours to complete the distance. It's important for beginners to pace themselves and take breaks as needed.
The time it takes to walk 3.8 km depends on your walking speed. On average, a person walks at a speed of about 5 km/h. At this pace, it would take approximately 45 minutes to walk 3.8 km. If you walk faster or slower, adjust the time accordingly.
The time it takes to cycle 80km can vary depending on factors like your speed, fitness level, and terrain. On average, it may take 2.5 to 4 hours to cycle 80km at a moderate pace of around 20-30 km/h.
To find the average speed, first calculate the total distance and total time. The total distance is 50 km + 30 km = 80 km. The total time is 20 minutes + 10 minutes = 30 minutes, which is 0.5 hours. The average speed is then total distance divided by total time: 80 km / 0.5 hours = 160 km/h. Thus, the average speed of the helicopter is 160 km/h.
The average during that period of time is 20 km/hour west .
To find the average speed of the train, you can use the formula: speed = distance/time. Here, the distance is 160 km and the time is 2.5 hours. Dividing 160 km by 2.5 h gives an average speed of 64 km/h.
around 110 km/h
The time it takes for a 12-year-old to cycle 10 km can vary based on their cycling ability, fitness level, and the type of terrain. On average, a child might cycle at a speed of 10 to 15 km/h. Therefore, it could take around 40 minutes to 1 hour to complete the distance. Factors like weather and bike type can also influence the time.
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.
