Answer:

Najeeb runs faster.

Step-by-step explanation:

Anna runs 5 minutes per km.

Therefore, in 5 mins she runs 1 km.

So, in 60 minutes she runs [tex]\frac{60}{5} = 12[/tex] km.

Therefore, the speed of Anna is 12 km/hour.

Again, Najeeb runs 8 miles per hour.

So, Najeeb runs (8 × 1.60934) = 12.87 km/hour.

{Since 1 mile is equal to 1.60934 km.}

Therefore, as 12.87 > 12, hence, Najeeb runs faster. (Answer)
