✔ 最佳答案

m/s = m/s * 3600/1000 = km/h

20 m/s
= 20 x 3600/1000
= 72000/1000
= 72 km/h

20m/s x 1km/1000m x 1hr/3600s = 20/3600000 = 0.0000056 km/hr

per 1 sec 20 miles--------therefore for 1 minute 20*60 = 1200 miles
per 1 hr 1200*60 = 72000 miles

conerting into km = 72000/1000= 72 km/hr

It is simple, Multiply it by 3.6

1m = 1/1000km and 1s = 1/3600hr
