1.	If a sprinter run a distance 1000 meters in 9.83 seconds.Calculate it's average speed in km/h.
Answer» Answer: 36.612 Explanation: DISTANCE travelled by SPRINTER = 100 m Time taken = 9.83 sec ∵speed = distance/time taken = 100/9.83 = 10.17 m/s Now we know, 1 km/h = 1000/3600 m/s so, 1 m/s = 3600/1000 km/h = 18/5 km/h ∴ 10.17 m/s = 10.17 × 18/5 = 10.17 × 18/5 = 36.612 km/h Hence, AVERAGE speed = 36.612 km/h

Answer»

Answer:

36.612

Explanation:

DISTANCE travelled by SPRINTER = 100 m

Time taken = 9.83 sec

∵speed = distance/time taken

= 100/9.83

= 10.17 m/s

Now we know, 1 km/h = 1000/3600 m/s

so, 1 m/s = 3600/1000 km/h = 18/5 km/h

∴ 10.17 m/s = 10.17 × 18/5 = 10.17 × 18/5 = 36.612 km/h

Hence, AVERAGE speed = 36.612 km/h
