## Starshine7 3 years ago Cyclist rode first 36 mile portion of his race at constant speed. For 27 cooldown portion he reduced his speed by 3 miles per hour. Each portion took same time, find cyclist speed during first portion and speed during cooldown. Show me how to set it up? Thanks.

1. King

let constant speed be v then, t=36/v fr 1st portion

2. Starshine7

36/x-3=27/x-3 Is this right?

3. King

fr 2nd portion let speed be v/3 so, t=27/(v-3)

4. King

no its 36/x=27/x-3
