Answer 2

Given:

Jessamine wants to ride her bike at least 85 miles per week.

Distance between her house and school = 6.25 miles.

Additional distance = 2.5 miles for each trip t.

Number of days = 5

To find:

The inequality for the given situation.

Solution:

Distance between her house and school = 6.25 miles.

Distance cover in the one day ride from house to school then school to house = 2×6.25 miles.

Distance cover in the five days day ride from house to school then school to house = 5×2×6.25 miles.

Additional distance = 2.5t

Total distance = 5×2×6.25 + 2.5t

Jessamine wants to ride her bike at least 85 miles per week. It means , total distance must be greater than or equal to 85.

`5* 2* 6.25+2.5t\geq 85`

Therefore, the required inequality is
`5* 2* 6.25+2.5t\geq 85`.
