Sound produced at a point is heard by a person after 5 second, while the same sound is heard by another person after 6 seconds. If the speed of sound is 300 m/s, what could be the maximum and minimum distances between the two persons?
1.8 km, 0.15 km
2.2 km, 0.20 km
2.8 km, 0.25 km
3.3 km, 0.30 km

Time difference of 2 persons is 1sec, it means distance between them is 300 m which is 3.3km, so option D is correct.

Distance=speed *Time
Distance(max)=1.8+0.15=1.95


Distance(min)=1.8-0.15=1.65

=1.95-1.65=0.3km

Use the formula DISTANCE = SPEED * TIME TAKEN.

For MAX add both & for MIN sub both.

Can you say the formula to be used to get the solution ? please!

@Annu Paraas.

300 m is equal to 0.3 km, not 3.3 km.
