Answer:

4.25 km (See Below)

Step-by-step explanation:

The question is:

How many kilometers did Nathan walk and jog?

Solution:

He walked 1/4th of 5 kilometer race

He jogged 3/5th of 5 kilometers race

Rest, he ran.

We need total km he ran and jog. That is (1/4) + (3/5)th:

[tex]\frac{1}{4}+\frac{3}{5}=\frac{5+3(4)}{20}=\frac{17}{20}[/tex]

So, we find 17/20th of 5, which is:

[tex]\frac{17}{20}*5=4.25[/tex]

So, Nathan walked and jogged 4.25 km of the race.
