Answer:
B
Step-by-step explanation:
To evaluate (f ○ f)(2) substitute x = 2 into f(x) and evaluate. Then substitute this value into f(x)
f(2) = 15 - 2 = 13, then
f(13) = 15 - 13 = 2
Hence (f ○ f)(2) = 2
The total distance travelled is 1075.91 km.
<h3>What is average speed?</h3>
The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
45 * (x +12)= 50* 1/5 + 1/2 *x
45x + 540= 10+ 0.5 x
44.5 x = 530
x= 11.91 (neglect the negative sign cause time can't be negative)
So, distance= 45* 23.91 = 1075.91 Km
