Answer:
The speed of the object at time, t=4 is
Step-by-step explanation:
The speed is calculated using the formula;
The distance covered by the object is given in terms of t, as
At time t=4, the distance covered by the object is;
The speed can now be calculated by substituting t=4 and distance 80 meters to obtain;
21-6n+2(2n-5)-3n
First, multiply 2x2n and 2x-5
21-6n+4n-10-3n
Then rearrange the terms
4n-6n-3n+21-10
Then combine like terms
-5n+11
