Answer:
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
HL(c) = a² + b² = c²
c = 9
c² = 18
√18= 4.24264068712
So! since this triangle is a "45° 45° 90°"
The two short legs are equivalent
meaning each side equals; <span>4.24264068712</span>
