Answer 1

Step-by-step explanation:

Given that:

Distance traveled (s) =84m

Time taken (t) = 5s

To Find :

Speed (V) =?

Solution :

As we know,

Speed = Distance traveled /time taken

=> Speed = 84/5 m/s

TO change m/s into Km/h

We have to put 1m = 1/1000km

And 1 sec = 1/ 60×60 h

Speed = 84×1/1000/5 ×1/60×60

Speed = 84 × 36/5×10

Speed = 84× 18/ 25 km/h

Answer 2

Answer:84/5=16.8km/h
