Question

Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains.Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by bike in a four week period if there is one rainy day each week.

Answer 1

1. d(4)(4) = 16d

Explanation:

let d be the distance

Number of non rainy days in week is (5-1) =4

Number of weeks = 4

in a week a student travels 4d

in 4 weeks a student travels 4×4×d = 4(4)(d)= 16d
