✔ 最佳答案

3300m=3300/1000=3.3km
10 seconds=10/3600=1/360 hours
speed=distance/time=3.3/(1/360)=3.3x360=1188 km/h

3300/1000=3.3km
10/(3600)=1/360h
3.3x360=1188km/h

1 h = 3600 sec

(3300 ／ 10) * 3600 / 1000 = 1188 km/h

一個鐘有3600秒，等於360個10秒，10秒走3.3km，360個10秒走多少？自己計。

distance= 3300/1000= 3.3 km
time= 10/(3600)= 1/360 h
speed= 3.3/(1/360)= 3.3x360=1188 km/h
