Question

A sprinter runs 100 metre in 9.83 seconds . calculate the average speed of the sprinter in km/h?​

Answer 1

Answer:

Total distance travelled =100m

Total time taken = 9.83 sec

Average speed = Total distance travelled

/ Total time taken =100/9.83 =10.172m/s

Averge speed in km/h: 10.172 x(3600/1000)=36.62 km/h

Explanation:

Answer 2

Step by step explanation :

Distance : 100 metre.

Time taken : 9.83 seconds.

$average \: speed \: = \frac{total \: distance}{total \: time}$

Average speed of the sprinter :

$\frac{100}{9.83} = 10.172 \: m {s}^{ - 1}$

Average speed in Km/h :

1m/s = 3.6Km/h

10.172 m/s = ?

= 10.172 × 3.6

= 36.6192 Km/h

The average speed of the shortest in Km/h is

36.6192 Km/h
