III. Numerical
1. A boy fires a gun and another boy at a distance of 1020m hears the sound of firing
the gun 3 seconds after seeing the smoke. Find the speed of sound.​

Answer 1

Explanation:

Distance = 1020 m

Distance = 1020 mTime taken = 3 seconds

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed=

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time taken

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled =

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled = 3

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled = 31020

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled = 31020

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled = 31020 =340ms

Distance = 1020 mTime taken = 3 secondsSpeed=\frac{Dis\tan ce\ travelled}{Time\ taken}=\frac{1020}{3}=340ms^{-1}Speed= Time takenDistance travelled = 31020 =340ms −1
