The men's world record for running a mile outdoors (as of 1999) is 3 min 43.13 s. At this rate, how long would it take to run a 5.00 km race? (1 mi = 1609 m)
Answers
Step-by-step explanation:
Given distance
= 1 mile
= 1609m
time taken = 3 min 43.13 sec
= 60×3 +43.13 sec
= 223.13 sec
speed = 1609/223.13
= 7.211m/s
now time in 5 km or 5000 m
= 5000×7.211
= 36055 sec
= 10 hours 55 sec
Answer:
Our runner can run 5km in 11.56 minutes.
Step-by-step explanation:
So, to convert km to miles multiply by 0.621371, this will give the miles travelled in km. Next we need the speed converted to seconds (decimal) 3.4313 Min per mile
3x 60 = 180 + 43.13 = 223.13 seconds,
5km x 0.621371 = 3.106855 miles,
Next to get how long it takes to go 3.1 miles we multiply by our time value.
223.13 x 3.106855 = 693.2325562 seconds total. Now the final equation,
693.2325562 / 60 = 11.55387594
So this converts seconds to minutes.
Our runner can run 5km in 11.56 minutes.
For comparison; I can run 10km in about 58 minutes.
