46.
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?

Distance of first person from the object: 300*5 = 1500 m=1.5km
Distance of second person from the object: 300*6 = 1800 m=1.8km
Max distance will be 1.5+1.8 =3.3 km (both are in opposit directions)
Min. distance will be 1.8-1.5 = 0.30 km (both are in same direction)
Distance of second person from the object: 300*6 = 1800 m=1.8km
Max distance will be 1.5+1.8 =3.3 km (both are in opposit directions)
Min. distance will be 1.8-1.5 = 0.30 km (both are in same direction)

Maximum distance = speed * time
= 300 * (6+5)
= 300 * 11
= 3300 m
= 3.3 km
Minimum distance = speed * time
= 300 * (6-5)
= 300 * 1
= 300 m
= 0.3 km
= 300 * (6+5)
= 300 * 11
= 3300 m
= 3.3 km
Minimum distance = speed * time
= 300 * (6-5)
= 300 * 1
= 300 m
= 0.3 km

DISTANCE = SPEED * TIME TAKEN
d1=300*5=1500
d2=300*6=1800
maximum distance=d1+d2
=1500+1800
=3300 metres=3.3km
minimum distance=d2-d1
=1800-1500
=300 metres=0.3km
d1=300*5=1500
d2=300*6=1800
maximum distance=d1+d2
=1500+1800
=3300 metres=3.3km
minimum distance=d2-d1
=1800-1500
=300 metres=0.3km

Use the formula DISTANCE = SPEED * TIME TAKEN.
For MAX add both & for MIN sub both.
For MAX add both & for MIN sub both.

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