Respuesta :
Based on the time taken to make one snowflake, the number of snowflakes that Amir can make in an hour and half is 18 snowflakes.
How many snowflakes can Amir make?
First convert the hours to minutes:
= 1 hour 30 minutes
= 1 + 30/60
= 1.5 hours x 60 minutes in an hour
= 90 minutes
Each snowflake takes 5 minutes to make:
= 90 / 5
= 18 snowflakes
In conclusion, Amir will have made 18 snowflakes.
