Answer:

210 minutes

Step-by-step explanation:

Jason's rate of peeling is ...

(15 potatoes)/(25 minutes) = 15/25 potatoes/minute = 3/5 potatoes/minute

Janette's rate of peeing potatoes is ...

(8 potatoes)/(6 minutes) = 4/3 potatoes/minute

Their combined rate is ...

(3/5 +4/3) = (9 +20)/15 = 29/15 . . . . potatotes/minute

Then the time required for 406 potatoes is ...

(406 potatoes)/(29/15 potatoes/minute) = (406×15/29) minutes

= 210 minutes
