You can put this solution on YOUR website! To do this problem, you have to know what a
relay race is. The runners runners run one
at a time. One after the other.
For 1st runner
(1)
For 2nd runner
(2)
given: m min min m/min m/min
-------------------------
Rewriting (1) and (2)
(1)
(2)
This is 2 equations and 2 unknowns, so it's solvable
(1)
(2)
(2)
Now add (1) and (2)
(2)
(1) min
And since min min
The 1st runner held the baton for 9.5 min, the 2nd for 9 min
check:
(1)
(2) m OK
