Ola runs 100metres in 10 seconds?

Question

what is his average speed in k/h

Answer 1

10 k/h

Answer 2

First you need to convert metres to kilometres and seconds to hours

So 100m is 0.1km (there are 1000m in 1km)

Now convert seconds to hours 10 seconds is 0.00277777778 hours (divide 10 by 60 (to get minutes) and again by 60 to get hours)

Average speed = distance travelled divided by time taken

So ave speed = 0.1km divided by 0.00277777778

Ave speed = 0.1 divided by 0.0027...

= 37.037km/h

Answer 3

There are 3,600 seconds in an hour so that's 100 meters multiplied by  360( because it's 110 meters in every 10 seconds not 1)  which is 36,000 m/h which is 36 km/h.

Answer 4

wow

Answer 5

the velocity would be 36 km/h

100m : 1000 = 0.1 km

10s : 3600 = 0.0027... h

km / h = 0.1 km / 0.0027.. h

           = 36 km/h
