Answer:

36 minutes

Step-by-step explanation:

2/3 = 40 minutes

1/2 = 30 minutes

14/15 = 56 minutes

= 126 minutes

They were supposed to get picked up after an hour and a half, 1:00 - 2:30, which is 90 minutes. Subtract 90 from 126 because 126 is their total time out and 90 is the supposed time. Your answer is 36.

Answer: The mom was waiting for half an hour (0.5 hours)

Step-by-step explanation:

They arrived in the mall at the 1:00 hs, and their mother said that she will be back at the 2:30 hs.

the difference between those is:

2:30hs - 1:00hs = 1:30hs

so the gilrs had one hour and 30 minutes to be in the mall. and knowing that 30 minutes is half an hour, we can write this as 1.5 hours.

now, she spended:

5/6 of an hour in the toy store

2/3 of an hour in the pet store

1/2 of an hour in the food court.

then in total we have:

5/6 + 2/3 + 1/2 = 5/6 + (2/2)*(2/3) + (3/3)*(1/2)

5/6 + 4/6 + 3/6 = 12/6 = 2

so the total time is two hours, this means that when they go back to the bench, their mom will be there for:

2hs - 1.5hs = 0.5 hs

half an hour.
