On a calm day with no wind, you can run a 1500-m race at a velocity of 4.0 m/s. If you run the same race on a day when you have a constant headwind that slows your speed by 2.0 m/s, how much time would it take you to finish the race

Answer :

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
