Question

You jog 2 kilometers in 12 minutes. At this rate, it will take______ minutes to finish a 5k race.

Answer 1

so 2 k:12
this is equal to 1k:6
so multipily by 5
5k:30
answer is 30 minutes assuming that you have superhuman stamina

Answer 2

I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
= 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
= 30 minutes
So it will take 30 minutes to finish a 5 kilometer race. I hope the procedure is clear to you.
