Jarry runs at 5mps so he would take
\(\frac{1000\ meters}{5\ Seconds}\) + 60 seconds of rest = 200 + 60 = 260 seconds
Ross runs at 4mps so he would take
\(\frac{1000\ meters}{4\ Seconds}\) = 250 senconds
So Ross wins the rase (Monika will be so proud to know
)
The correct answer is B
\(\frac{1000\ meters}{5\ Seconds}\) + 60 seconds of rest = 200 + 60 = 260 seconds

It takes Jerry 1000/5 = 200 seconds to finish the race if he doesn’t take a break. However, since he takes a one-minute break, it takes him 200 + 60 = 260 seconds to finish the race.
Since it takes Ross 1000/4 = 250 seconds to finish the race (which is less than Jerry’s time of 260 seconds), Ross is the winner.
