the elimination round for mathematics olympiad lasted for 2 1/2 hours. If it started at 8:45 am, what time did it finish​

Sagot :

Answer:

11:15 AM

Step-by-step explanation:

8 hours and 45 minutes + 2 hours and 30 minutes

10 hours + 75 minutes

(Take note that 60 minutes = 1 hour.)

75 minutes ÷ 60 minutes

= 1 hour and 15 minutes

Now, add.

10 hours + 1 hour and 15 minutes

= 11 hours and 15 minutes

Therefore, elimination round for mathematics olympiad finished at 11:15 AM.
