100 m / s
​

Answer 1

Answer:

20Km/ hr

360 Km / hr

Step-by-step explanation:

100m in 18 sec

Distance covered in 18 sec = 100m

Distance covered in 1 sec = 100 ÷ 18 m

Distance covered in 60 sec = 100 ÷ 18 × 60

Distance covered in 60 min = 100 ÷ 18 × 60 × 60

= 20000m

= 20Km/ hr

100m / sec

100 × 60 m / min

or

100 × 60 × 60 m / hr

360000m / hr

360 Km / hr
