Answer:
Cookie monster needs to steal at least 6 cookies more.
Step-by-step explanation:
Given:
Number of cookies already stole = 4
Total number of cookies he wants to steal
We need to find how many cookie he needs to steal more.
Solution:
Let number of cookies he needs to steal more be 'x'.
Now we can say that;
Number of cookies already stole plus number of cookies he needs to steal more should be greater than or equal to Total number of cookies he wants to steal
framing in equation form we get;
Now using Subtraction property of Inequality we will subtract both side by 4 we get;
Hence Cookie monster needs to steal at least 6 cookies more.
The required distance is 16.40 km.
This problem can be solved if we know the concept of speed, time and distance.
We know the speed=
To solve the problem let us assume that the total distance between the workplace and home is x km.
Given that his speed while going from home to work is 45 mph and while returning is 35 mph.
Time for the complete journey is .
Now according to question;
⇒
⇒
⇒
∴
So, the required distance is 16.40 km.
