The woman's average speed during her entire motion is 73.15 meter/minutes.
<h3>What is speed?</h3>
The speed is the total distance traveled by the object in a unit time interval.
Mathematically,
Average speed = Total distance/Time
Now it is given that,
Total time taken by the women = 60 + 25 minutes
⇒ Total time taken by the women = 85 minutes
Now for distance covered by women during her southward direction
= speed x time
= 2 mph x 60 minutes
∵ 60 minutes = 1 hour
and 1 mile = 1.609km
∴ Distance (southward) = 2 mph x 1 hour
⇒ Distance (southward) = 2 miles
⇒ Distance (southward) = 2 x 1.609 km
⇒ Distance (southward) = 3.218 km
Now it is given, distance travelled northward = 3000m + 3 km
So, Total distance = 3.218 + 3 km = 6.218km = 6218 meters
and total time = 60 + 25 minutes = 85 minutes
Hence, Average speed = 6218/85 meter/minutes
⇒ Average speed = 73.15 meter/minutes
Hence, the woman's average speed during her entire motion is 73.15 meter/minutes.
