Answer:

£11.43

Step-by-step explanation:

£2.65x2=£5.12

£1.15×3=£3.45

£5.12+£3.45=£8.75

£20.00-£8.75=£11.43

The mistake was in the first line of your answer, you multiplied by 3 instead of 2.

Rashid [163]

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

$5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55$

Dividing both sides by 5

$\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11$

Marcus needs to bike at least 11 miles each day.
