Patty goes to the mall at 9:30 am and meets a friend at a movie at 11:15 am. Patty wants to shop and have 55 min for lunch before meeting her friend
How much time can patty spend shopping?

50 minutes

Step-by-step explanation:

Time when patty goes to mall = 9:30 am

Time when he has to meet a friend = 11.15 Am

Spare time patty has is interval between Time when he has to meet a friend

and Time when patty goes to mall

which can be written as

Spare time patty has = 9:30 am to 10:30 am which is 1 hours 45 mins.

One hour has 60 minutes.

Thus total time in minutes patty has = 1*60 minutes + 45 minutes = 105 minutes.

Time which will be used by Patty to have lunch = 55 minutes.

Time left out if 55 minutes are used in lunch = total spare time - time for lunch = (105 - 55 ) minutes = 50minutes.

Patty wants to shop in the spare time after allocating 55 minutes to lunch.

Thus the rest of time which is 50 minutes, he can use to shop.
