Annie spent 1 hour 15 minutes at the dance class and 1 hour 30 minutes at the art class. Where did she spend more time? a. Dance Class b. She spent the same time at both the places c. Art class

Solution:

To find where Annie spent more time, one should compare the time she spent at both places.
[Compare the hours she spent.]

As it is 1 hour in both the places.
[Compare the minutes.]

15 minutes is less than 30 minutes.

As, 1:30 minutes is more than 1:15 minutes, we can conclude Annie spent more time at the art class.

Solution:

The time spent for break fast + the time spent for lunch + the time spent for dinner
[The sum of duration of all the activites gives the total time spent.]

= 30 minutes + 30 minutes + 30 minutes
[Add the time spent on each activity.]

60 minutes + 30 minutes
[Express minutes as hours.]

=1 and 1 / 2 hours
[Since 60 minutes = 1 hour and 30 minutes = 1 / 2 hour.]
