Question

A 300m long train cross a pilar in 18 seconds. Find the speed of train in km/h.​

Answer 1

Answer:

60 km/h

Step-by-step explanation:

m/s to km/h = 18/5

300/18 × 18/5

300/5 = 60

Answer 2

Answer:

the train takes 18 seconds to travel 300m (since the pole is at rest.)

thus speed of the train is

$(300 \div 18)m {s}^{ - 1 } \\ = (300 \div 18) \times (18 \div 5) \\ = 300 \div 5 = 60 \frac{km}{h}$

hope it helps.
