Scott and Harry went cycling every day. They increased the number of minutes of cycling every week as described below:

Scott: Cycled for 10 minutes every day in the first week, 15 minutes in the second week, 20 minutes in the third week, and 25 minutes in the fourth week.

Harry: Cycled for 10 minutes every day in the first week, 20 minutes in the second week, 40 minutes in the third week, and 80 minutes in the fourth week.

Which statement best describes the methods used by Scott and Harry to increase the time they spent cycling?

Answer 1

Choices:
Scott's method is linear because the number of minutes increased by an equal number every week.
Harry's method is linear because the number of minutes increased by an equal factor every week.
Both Harry’s and Scott's methods are exponential because the number of minutes increased by an equal factor every week.

Answer 7

unfortunately not...harry doubled his time each week...that is not linear it is....

Answer 8

c?

Answer 9

no...Scott increased his time by five minutes a week...would we describe that as linear or exponential?

Answer 10

exponential since you said that harry doubled his time each week and it is not linear...

Answer 11

sorry I have a hard time with algebra

Answer 12

that is ok...
Harry is exponential because he doubled his time each week
Scott added 5 minutes per week which is linear

Answer 13

so then that would mean that the answer is A
