Question

EspelLucy and Aldo each ran every day as part of an exercise routine. Lucy ran 3 miles each day for x days. Aldo ran 6 miles each day for y days.The total number of miles that Lucy ran is greater than the total number of miles that Aldo ran. Write an inequality describing this relationship.

Answer 1

Given:

Lucy ran 3 miles each day for x days.

So, for x day the total number miles will be,

`3x`

Aldo ran 6 miles each day for y days.

For y days the total miles are,

`6y`

The total number of miles that Lucy ran is greater than the total number of miles that Aldo ran.

The inequality is,

`\begin{gathered} 3x>6y \\ \text{Simplify it} \\ x>2y \end{gathered}`

Answer:

`3x>6y\text{ or x>2y}`
