PLEASE SOMEONE ANSWER MY QUESTION
The exponent is a positive number, so you move the decimal point, that many places to the right:
3.276 x 10^9 = 3,276,000,000
From the information, the mean temperature for January is most likely lower than the mean temperature for March.
There are a couple of clues to this assumption. First, the max temp is lower for January. Second, the interquartile range is lower in March. With both of these factors, it is safe to assume the mean is lower.
There is no way that he can run 151515km/h, but if he really can, then :
1 hour = 60 minutes
(151515km/h)/60minutes = 2525,25km/minute
