The graph of the journey is shown in the speed-time graph below
At the time = 3 minutes, Peter would have achieved the speed V.
The distance he travelled is the area under the line as shown in the graph
We first need to find the V by using the area of a rectangle formula
so V=220
the gradient the f slope then given as
Answer: {y/y>-4}
Step-by-step explanation:
<h3>
Answer: 1320 (choice C)</h3>
Explanation:
There are 12 choices for left field.
Then there are 12-1 = 11 choices for right field.
Lastly, there are 11-1 = 10 choices for center field.
In total we have 12*11*10 = 1320 different permutations or orderings.
