Question

It takes Kasey 55 minutes to walk to school. When she starts her route. It takes her 14 minutes to get to the corner where the grocery store is. It takes her another 22 minutes to get to the Pist Office. How much longer does she have to get to school without being late

Answer 1

add the time to get to the grocery store and then to the post office:
14 + 22 = 36 minutes
subtract that time from the total time it takes her:

55 - 36 = 19

she has 19 more minutes to get to school
