When a  woman walks south at a speed of 2.0mph for 60 minutes. She then turns around and walks north at a distance of 3000m in 25 minutes. then the woman's average speed during her entire motion would be  73.15 meters /minute.
<h3>What is speed?</h3>
The total distance covered by any object per unit of time is known as speed.
the mathematical expression for speed is given by
speed = total; distance /total time 
As given in the problem a woman walks south at a speed of 2.0mph for 60 minutes
60 min = 1 hour 
1 mile = 1.60934 km 
The distance covered by her southwards  =  speed ×time 
                                                                       =2 mph × 60 minutes 
                                                                       = 3.218 km 
She then turns around and walks north at a distance of 3000m in 25 minutes
The distance covered northward is 3000m
speed = total distance /total time 
           =(3218 +3000) /(60+25)
           =73.15 meters /minutes 
Thus, The average speed of the woman would be 73.15 meters /minute.

A bees wings move so rapidly that studying them, even seeing them, has proved difficult.
The honeybees have a rapid wing beat honeybee flaps its wings 230 times every second.
Therefore, a bee flaps its wings over 200 times in about 1ms
