Answer:
I'm PRETTY SURE your answer is A
Explanation:
Evaporation of water is greater during the summer, because of the sever change of temperature (Depending where you live) and the increase of light rays on the earths surface, and bodies of water.
There are 60 minutes in an hour. Whatever distance a person crosses in 5 mins, he/she can cross 12 times that distance in 1 hour. So, in one hour the person could have crossed 12 X 600 = 7200 meters.
But, 1000 meters equal one kilometer. So, 7200m = 7.2 km. Thus, this person travels 7.2 km in one hour, and hence has a speed of 7.2 km/hr
The answer is B. 2
