Ответ:
4 and 1/2 hours or 270 minutes
Step-by-step explanation:
Each student spend 30 minutes to set up the puppet show.
+30
They spent twice as long to put everything away.
+30 +30
Current total: 90 minutes
The show was open for three hours
+180 (60 minutes in an hour x 3 hours)
Current total: 270
Total: 270 minutes
OR
Divide 270 by 60 minutes in an hour, which would be 4.5 hours.
Ответ:
1 hour and 30
Step-by-step explanation:
First, you multiply 30 minutes x2 and get 60. 60 minutes is an hour so now you have an hour. Then you add 30 minutes to that and get 1 hour and 30 minutes. Then, you subtract 3 hours minus 1 hour, and 30 minutes and get 1 hour and 30 minutes.
Ответ:
3 Apples = 90p
2 Bananas = 50p
= £3.20
£3.65 - £3.20 = 45p
45p / 15p = 3.
So the answer is 3 Pears
