Respuesta :
Marcus needs to bike at least 11 miles each day.
Step-by-step explanation:
Given,
Distance to cover = 80 miles at least
Distance already biked = 25 miles
Number of days left = 5
Let,
x be the distance to cover in 5 days.
According to given statement;
Number of days left * Distance to cover + distance already bike ≥ Total distance to travel
[tex]5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11[/tex]
Marcus needs to bike at least 11 miles each day.
