Jasper decorates flower pots to sell in his shop. HE knows that it takes 12 minutes to decorate a flower pot.

Jasper works from 9:30am until 12:50pm on Tuesday.
HE takes 20 minutes for a coffee break at 10:30am

How many flower pots does Jasper decorate on Tuesday?

15 flower pots

Step-by-step explanation:

9:30 until 12.50=3 hours and 20 minutes or 200 minutes

200 minutes - 20 minute break=180 minutes working

180/12=15 pots

He works from 9:30am to 12:50pm.

He takes a brake at 10:30 for 20 mins.

Now the time he works will be

(12:50 - 9:30) - 20

3:20 - 20

3:00

NOTE: TILL HERE DONT THINK THE SIGN ':' IS USED FOR RATIO, ITS USED AS IN TIME. AND THIS MEANS THE NUMBER BEFORE ':' IS HOURS AND THE NUMBER AFTER THE ':' WILL BE MINUTES.

i.e., 3 hours.No. of pots decorated in 3 hours will be,

3 hours in minutes÷time taken to decorate one pot.

⇒ (3×60)÷12

⇒ 180÷12

⇒15

Thus he decorates 15 pots in the given time.
