If you divide the distance by the time, you'll get the average speed. In this case, the answer will be in km/hour.
The average speed during that time is 20 km per hour. We can't say anything aboutthe velocity because you've told us nothing about the direction it traveled."Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.

30km/h = 30km/60min = 5km/10min 20km/h = 20km/60min = 10km/30min 5+10=15km
20 / 36:37 = 32.77 KPH / 60, or 20.36 mph.
If you divide the distance by the time, you'll get the average speed. In this case, the answer will be in km/hour.
15km/h
Average speed = Distance/Time = 20/5.17 = 3.87 km per minute.
45km/h because you add the two speeds together and divide. so 50+40=90/2 = 45
20km/hr
To do this, you need to form equations using the information given. There are 2 variables here, the base speed of the rower with no current (x), and the speed of the current (y). Firstly, convert the distances and times given into average speeds. 20km/2 hours = 10km/h 4km/2 hours = 2km/h The actual speed = the base speed +- the current, depending on direction. So 10 = x + y 2 = x - y If we subtract these 2 equations to eliminate x, we get: 8 = 2y y = 4km/h
The average speed during that time is 20 km per hour. We can't say anything aboutthe velocity because you've told us nothing about the direction it traveled."Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.

An African Lemur's top speed is 20km/h (12mph)
20km over the speed limit will incurr immediate loss of license
