Excel公式可从距离和速度获取时间

Question

我需要一个公式来从距离（km）和速度（kt）中获取时间

A1 = 100km (distance)
A2 = 40knot (speed)
A3 = 00:00:00 (time) which I need!?

有人知道热卖这个吗？谢谢

UPDATE - Solved!
Knots should be first converted to km/h. So formula is =(100/(40*1,852))/24

Answer 1

使用代数：解决时间。由于D = rt求解t; t = D / r。换句话说，A3 = A1 / A2。
