Benjamin Franklin · Answer 1

70 clicks in 20 seconds

Step-by-step explanation:

The speed of the train in mile per hour is approximately the number of clicks heads in 20 seconds.

Each click shows that the train has travelled 30ft

1 click per second is = (30ft/sec = 3600 * 30) / 5280

20.45mph approximately 20mph

Therefore

20mph = 20 clicks in 20 s

30mph = 30 clicks in 20s

70mph = 70 clicks in 20s
