Question

A large procession of people is moving along a road of width 10 m . There is a railway track across the road. The number of people present per square meter of the road is 6 (on an average). The average speed at which the procession is moving is $0.15 m / s$ . Find the number of people crossing the railway track per second.

Answer:

9

Solution:

no. that will cross in $Δ t$ time $Δ n$ $Δ n = 10 \times (0.15Δ t) \times 6$ $\frac{Δ n}{Δ t} = 9$
