Answer :

Person 2 jogs faster as compared to person 1.

The time taken by the faster jogger finish a five-kilometer race will be, 27.5 minutes.

Step-by-step explanation :

First we have to calculate the speed of person 1 and 2.

Formula used :

Speed=\frac{Distance}{Time}

\text{Speed of person }1=\frac{Distance}{Time}=\frac{2km}{12min}=0.167km/min

and,

\text{Speed of person }2=\frac{Distance}{Time}=\frac{3km}{16.5min}=0.182km/min

From this we conclude that, person 2 jogs faster as compared to person 1.

Now we have to calculate the time taken by the faster jogger finish a five-kilometer race.

Faster jogger speed = 0.182 km/min

Distance = 5 km

Speed=\frac{Distance}{Time}

0.182km/min=\frac{5km}{Time}

Time=27.5min

Thus, the time taken by the faster jogger finish a five-kilometer race will be, 27.5 minutes.
