2 metres in 100 seconds = 200 centimetres in 100 seconds = 2 cm per second.
40 mph
The average speed.
To find average speed, divide the distance travelled by the time it takes to travel that distance. In this instance, 60 / 3 = 20. Therefore, you would need to travel at an average speed of 20 miles per hour.
3000 m in 20 sec = 9000 m in 1 min which in turn = 540000 m in 1 hr or 540 kph
15 m/s
2 metres in 100 seconds = 200 centimetres in 100 seconds = 2 cm per second.
That depends a lot on the speed.

Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?
Average Speed = distance/time = 240/4 = 60 mph
40 mph
The average speed.
To find average speed, divide the distance travelled by the time it takes to travel that distance. In this instance, 60 / 3 = 20. Therefore, you would need to travel at an average speed of 20 miles per hour.

Average human waking speed is 1.4m/s. Thus, the average time it takes, at walking speed, to walk 1km is 11 minutes, 54 seconds.
