Question

Hannah reads at a constant rate of 3 pages every 8 minutes.

Write an equation that shows the relationship between p, the number of pages she reads, and m, the number of minutes she spends reading.

Answer 1

The equation is:

number of pages=reading speed×number of minutes

p = 3/8 × m

The correct answer is

p=3/8 m

Answer 2

`m=(8)/(3)p`

Explanation:

`\begin{array}{ccc}3\ (pages)&-&8\ (min)\\p\ (pages)&-&m\ (min)\end{array}\qquad|\text{cross multiply}\\\\p\cdot8=3\cdot m\qquad|\text{divide both sides by 3}\\\\m=(8p)/(3)`
