1 of 3 kids was a boy, so (1/3)·75 = 25 were boys.
Time taken to reach a person located 5m from the source is 0.2s
<u>Explanation:</u>
Given:
Frequency, f = 10Hz
Wavelength, λ = 2.5m
Distance, d = 5m
Time, t = ?
We know:
velocity = f X λ
v = 10 X 2.5
v = 25 m/s
We know:
Distance = speed X time
On substituting the value we get:
5 = 25 X t
t = 0.2 seconds
Therefore, time taken to reach a person located 5m from the source is 0.2s
Since the graph is moving positive from left to right, x is positive. so now we are left with B) and C) for our answer
now, the y intercept or b is -3 as shown in the graph
the answer is C) y= x -3
