You can put this solution on YOUR website! A triathlon includes a .5 km swim, 40 km bike, and a 10 km run.
Mr. B completed the swim in 25 minutes and 10 seconds,
and the bike ride in 1 hour, 30 minutes, and 50 seconds.
If he wants to equal the triathlon record of 2 hours and 46 minutes, how fast must Mr. B run in meters per second?
:
Find the total for the first two events
0h 25' 10"
1h 30' 50"
-----------
1h 55' 60" which is 1h 56 min
:
Find the time allotted to the run
2h 46" > 1h 106"
1h 56" > 1h 56"
----------------
50 min for the run
:
"how fast must Mr. B run in meters per second?"
50 * 60 = 3000 seconds, and 10*1000 = 10000 meters
speed = dist/time
s = 10000/3000
s = 3 meters/sec
