Answer:

Step-by-step explanation:

A is incorrect because the range of the data is basically just subtraction. The range of 20-40 year old men's heart rates are higher than 50-70 year old men. B is incorrect. Think of "median" as "middle". The heart rates of the 20-40 year old men is higher than the heart rates of the 50-70 year old men. C is incorrect, because the minimum heart rate is the "starting point" of the box plot, in these cases for the 20-40 year old men, that would be 75, which is higher than the 50-70 year old men.

The distance between city A and B is 600 km. The first train left A and headed towards B at the speed of 60 km/hour. The secon

$\bf \textit{meaning}\implies

600-d=(v)(t+3)\\

d=\boxed{60t}\qquad thus

600-\boxed{60t}=v(t+3)\leftarrow \textit{solve for "t"}
\end{cases}$

keep in mind, that "t" is the time when the train at A station, left towards B station

they met, at some time "t", and by the time that happened, train from A
which started 3 hours earlier, had already covered "d" distance,
whatever that is
and the train coming from B, covered, 600-d, or the difference
