Defiantly need with this one and explain

1.05833333 × 10-7 m/s  

Or

15 mph

Step-by-step explanation:

7.5+4.5=12

12 miles per 48 min

1.05833333 × 10-7 m/s  

Or

12/48 = 1/4

1/4 x 60 = 15

15 mph

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
