1)time taken by sound wave to reach bottom of sea= 1 second
speed =1.5km/sec
speed = distance / time
distance = speed * time
= 1.5*1=1.5km
2)distance of cliff from 1st men=150m and time of sound wave=1 second
speed of wave= 150/1=150m/s
distance travelled by wave to reach second man= 150+150+300=600m
echo time= 600/150=4second
I. e. option (D)
