What have you tried? Where are you stuck?Can someone please show me the steps needed to achieve the answers to this question?
Leonard need to get to Penny's house from his apartment- her house is just across a 4km wide river and is 3km upstream from Leonard's apartment with a current of 1km/h toward the east. Leonard can do one of two things: 1) he can swim on a path straight to Penny's house or 2) he can swim straight across the river and run the rest of the way on land. His swimming speed is 4km/h and his running speed is 6km/h. Which method will get Leonard to Penny's the fastest?
any help is much appreciated. =)
