Question

Matthew is training to participate in a half marathon. The table below shows the number of miles he runs in weeks 1 and 2.

Answer 1

Matthew ran 14.58 miles in week 3

Answer 2

Answer:

14.58 miles.

Step-by-step explanation:

Matthew is training to participate in a half marathon.

The distance covered by Matthew on the first day is 12.5 miles.

The distance covered by Matthew on the second day is 13.5 miles.

The distance increased on the second day is, $13.5-12.5=1$ mile.

The percentage will be,

$=\dfrac{1}{12.5}\times 100\%$

$=0.08\times 100\%$

$=8\%$

Hence, each day he runs 8% more. So the distance covered by him on day 3 will be,

$=13.5+\left(13.5\times \dfrac{8}{100}\right)$

$=13.5+1.08$

$=14.58$ miles
