<u>Ans(a):</u>
Given that total distance = 1158 km
Estimated time of drive = 12
now question says to distance that can be driven in 1 hour.
Indirectly it is asking for his speed.
So we can use formula of speed
km per hour.
Hence he will drive approx 96.5 km in 1 hour.
<u>Ans(b):</u>
Actual driven distance = 484 km
Actual time taken = 5 hours
Then actual speed km per hour
Comparing speeds in both parts, we see that actual speed 96.8 km/hour is more than the expected speed 96.5 km/hour.
Hence he will reach at his destination on schedule or before the expected time.
Answer: 7
Step-by-step explanation:
To find the absolute minimum we must first take the derivative of the function and find where it equals zero. From there we can use the first derivative test to find where our possible minimum is. We then will test each endpoint and compare for the minimum for this function.
The lowest value is 7. The absolute minimum of this function is 7. If you were to graph it, we'd see that the graph reflects that as well.
