Using the relation between velocity, distance and time, it is found that his jogging rate was of 4.5 mph.
<h3>What is the relation between velocity, distance and time?</h3>Velocity is <u>distance divided by time,</u> hence:
Jogging, his velocity was of v, while the time was of t + 2, for a distance of 10 miles, hence:
Riding, his velocity was of 16, while the time was of t, also for a distance of 10 miles, hence:
Then, considering the first equation and replacing in the second:
16t² + 32t - 20 = 0 -> t = 0.5.
Then his jogging rate in mph was:

Hi there,
I’m attaching the same image with more information on the graph.
The 4th mark (the middle dashed line) is marking the mean (70).
The 3rd and the 5th are marking the mean less/plus 1 deviation.
So, 70.5 is the 5th mark.
Taking this into account:
The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%
The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%
Good Luck!
