The movement of air flows from high pressure to low pressure
4 water has a low heat capacity and a high vaporization temperate and coasts have low temps
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.
