____________________________________________________
Step-by-step explanation:
We are trying to combine like terms with the expression: -k - ( - 8k)
We are pretty much solving it.
Solve:
-k - ( - 8k)
The "- ( -" turns into a plus sign.
So it would look like:
-k - -8k or -k + 8k
Now, you would finish solving
-k + 8k = 7k

Answer:
The two planes have traveled the <em>same distance.</em>
Step-by-step explanation:
Given that:
Velocity of first plane traveling north = 100 km/h
Time taken by the plane = 2.5 hours
Velocity of second plane traveling north = 62.5 km/h
Time taken by the plane = 4 hours
To find:
Which plane traveled longer distance?
Solution:
First of all, let us have a look at the formula for finding the distance using velocity and time.
Formula is:
Distance traveled by first plane:
Distance traveled by second plane:
Here, we can clearly see that:
Therefore, the two planes have traveled the <em>same distance</em>.
