Ответ:
If Koby can work 22 math problems in 30 minutes, then he can work 44 in an hour (multiply your problems completed and time elapsed by 2).
Now, we have to figure out how many he can complete in 3 hours, so all we have to do is multiply our current math problems by 3.
44 * 3 = 132
This means that Koby can complete D.) 132 math problems in 3 hours.
I hope this helps!
Ответ:
The answer would be D.
30 minutes = 22 math problems.
1 hour = 44 math problems.
44 x 3 = 132 math problems.
So, D is your answer.
Hope this helps ;)
