Answer:
The time that pass until only two cookies left is 1.89 hour
Step-by-step explanation:
Given as :
The number of cookies bakes in 2 hours = 3 dozen
∵ 1 dozen = 12 piece
So, In 3 dozen = 12 × 3 = 36 cookies
The Time required to bake 36 cookies = 2 hours
Now, Let The time required to bake 2 cookies = x hour
So, According to question
∵ The time required to bake 36 cookies = 2 hours
So, the time required to bake 1 cookies = =
hour
∴The time required to bake 34 cookies = × 34
I.e The time required to bake 34 cookies = hour = 1.89 hour
Or, the time taken is 1.89 hours
Hence The time that pass until only two cookies left is 1.89 hour Answer
