Marilyn and tiara went for jogging every day. they increased the number of minutes of jogging every week as described below: marilyn: jogged 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. tiara: jogged for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week. which statement best describes the methods used by marilyn and tiara to increase the time they spent jogging? marilyn's method is linear because the number of minutes increased by an equal factor every week. tiara's method is linear because the number of minutes increased by an equal number every week. both tiara's and marilyn's method is exponential because the number of minutes increased by an equal number every week. both tiara's and marilyn's method is exponential because the number of minutes increased by an equal factor every week.

Tiara's method is linear because the number of minutes increased by an equal number every week.

Step-by-step explanation:

Marilyn: Jogged 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.

Her increase is exponential as we can see that the next time is two times the earlier time.

Tiara: Jogged for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week.

Her increase is linear in nature as it is gradually increasing with value 10.

So, as per the situation, the correct answer will be - Tiara's method is linear because the number of minutes increased by an equal number every week.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
