Answer:
Answer = He spent 77 minutes completing the marathon.
Step-by-step explanation:
[tex]\frac{4}{7}[/tex] is the ratio. We need to know the amount of time he jogged.
So [tex]\frac{4}{7} =\frac{28}{x}[/tex] x is the amount of time he jogged. Solve this equation and cross multiplying and you'll get x = 49. So he jogged for 49 minutes. Now add 28 and 49 and you'll get 77 minutes. Hope this helps!
