Patty and Betty have the same 5th and 6th period classes. Patty rushes to get to 6th period--she takes 21 seconds to get there! Betty hates that class, so she does not rush... it takes her 2 minutes to get there. Patty uses a force of 80 N, and Betty uses a force of 60 N. Their 6th period class is 24 m away from their 5th period. Calculate the power for Betty:
