Question

Jenna has already cycled 8 kilometers this year,plus she plans to cycle 2 kilometers during each trip to work.Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.

Answer 1

`d = 8 + 2t`

Explanation:

Given

`Rate = 2km/trip`

`Base\ Cycle = 8km`

`d = total\ distance`

`t = cycles`

Required

Determine the expression for this scenario

The expression can be derived from:

`Total\ Distance = Base\ Cycle + Rate * Cycles`

Substitute d for Total Distance and t for cycles

`d = Base\ Cycle + Rate * t`

Substitute values for Base Cycle and Rate

`d = 8 + 2* t`

`d = 8 + 2t`
