To find the average speed, you divide the distance by the time taken. In this case, the distance is 3 kilometers and the time is 15 minutes. First, convert 15 minutes into hours, which is 0.25 hours. Therefore, the average speed is ( \frac{3 \text{ km}}{0.25 \text{ hours}} = 12 \text{ km/h} ).
I think you mean 3 kilometers per 7 minutes. speed = distance/time = 3km/7min = 0.5km/min (rounded to 1 significant figure) If you did mean 7min per 3km, it would be 7min/3km = 3min/km (rounded to 1 significant figure)
21 km/7 hours = 3km/hour
3km in 20 minutes, therefore in 60 minutes (1 hour) you will travel 9km {(3 x 60)/20}

Basic Formulaspeed = distance/timeDerived Formulatime = distance/speed = 3km/11km/h = 0.27h, which is a little more than 16min.
3km/12min = 0.25km/min
10 minutes on average

In order to find an average velocity, you need an average speed and an average direction. Average speed = (distance traveled) divided by (time to travel that distance) Average direction could be defined as the direction from the starting point to the end point.
It depends at what speed you drive
Speed = Distance/Time Speed= 3000m/600 seconds Speed= 5m/s or 11.1846815 mph
Robert walks from town A to town B, he must pass a hill and a section of a flat road. His speed of walking uphill is 3km/hour, on a flat road is 5km/hour and a downhill is 6km/per hour. Robert's average speed from town A to town B is 4.2.km/hour. What is his average speed from town B to town A?
The time it takes to walk 0.3 km depends on your walking speed. On average, a person walks at about 5 km/h, which means it would take approximately 3-4 minutes to cover that distance. If walking at a slower pace, it might take a bit longer.
