Given the statement:
Kathie ran for twice as long as she walked. She walked for 10 minutes more than she rode her bike. She walked for 30 minutes.
Determine how many minutes did Kathie Exercise.
Solution:
Since it is stated that Katie walked for 10 minutes more than she rode her bike, and if she walked for 30 minutes, then she rode her bike for 20 minutes. It is also stated that Kathie ran twice as long as she walked, therefore she ran for 1 hour or 60 minutes. Now we can determine the number of minutes that Kathie exercised by simply adding the values that we've analyzed.
= 30 minutes + 60 minutes + 20 minutes
= 110 minutes
=1 hour and 50 minutes
Final answer:
Kathie exercised for 1 hour and 50 minutes.
