(27 mi/hr) x (1 hr / 60 min) = (27/60) (mi/min) = 0.45 mile/minute
Using the same kind of calculation, we can see
that the world record times for other distances
correspond to:
200 meters 23.31 mph
400 meters 20.72 mph
800 meters 17.73 mph
1000 meters 16.95 mph
1500 meters 16.29 mph
1 mile (1,609 meters) 16.13 mph
2,000 meters 15.71 mph
10,000 meters 14.18 mph
30,000 meters 12.89 mph
Marathon (42,195 meters) 13.10 mph
Except for that one figure at the end, for the marathon,
which I can't explain yet and I'll need to investigate further,
it's pretty obvious that a human being, whether running for
his life or for a gold medal, can't keep up the pace indefinitely.

Step-by-step explanation:it B
It appears Jake said 5-2 = 3 for the denominator portions. This is not correct. In order to subtract fractions, the denominators must be the same and they stay the same the entire time. Only the numerators (aka stuff up top) are being subtracted.
Currently 3/5 - 1/2 cannot be subtracted since the 5 and 2 are different denominators. But we can say this:
3/5 = 6/10
1/2 = 5/10
and then from there, we can say:
3/5 - 1/2 = 6/10 - 5/10 = (6-5)/10 = 1/10
So in short,
3/5 - 1/2 = 1/10
Step-by-step explanation:
Given that,
The length of a carton, h = 9 cm
Width, b = 13 cm
height, h = 24 cm
I drink one-third of the fruit juice, then two third will be left. So, the volume is :
Since, 1 L = 1000 cm³
1872 cm³ = 1.8 L
or
= 1800 mL
Hence, this is the required solution.
