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.
