Answer:

The required time is 750 s.

Explanation:

The velocity of the man gets slowed by 2.0 m/s when the wind is blowing.

Therefore the speed of the man on the day of wind is (4.0-2.0)=2.0 m/s.

The time, speed and distance are related by the equation,

t=v/d

Given v= 2 m/s and d=1500 m.

The required time is,

t=1500/2

t=750 s

Answer:

The time taken to finish the race is 750 s.

Explanation:

The velocity of the person on the day of wind is slowed down by 2.0 m/s. So the person's velocity on the day of wind is 4-2=2 m/s.

The relation between time, speed and distance is t=v/d

Given d=1500 m and calculated v= 2 m/s.

t=1500/2

t=750 s.
