16. Question 17A cheetah was running at 5 km per hour for ten seconds until it spottedan impala it wanted to catch. The cheetah then run faster and averagedto 60 km per hour for the next 40 seconds. The impala went away andthe cheetah slowed down to an average of 5 km per hour for ten seconds.Rounded to the nearest km per hour, what was the cheetah's averagespeed for the entire minute?A. 54 km/hB. 50 km/hC. 46 km/hD. 42 km/hE. 35 km/h.
Jawab:
For 10 seconds a cheetah running at 5km/h.
Then it run faster and averaged to 60km/hr for 40 seconds.
Then it slowed down to an average of 5km/h for 10 seconds.
The calculation will be like this:
10 seconds = 1/6 minute
40 seconds = 4/6 minute
60 seconds = 1 minute
Distance / Time
= {([tex]\frac{1}{6}[/tex] × 5) + ([tex]\frac{4}{6}[/tex] × 60) + ([tex]\frac{1}{6}[/tex] × 5)} / 1
= ([tex]\frac{5}{6}[/tex] + [tex]\frac{240}{6}[/tex] + [tex]\frac{5}{6}[/tex])
= [tex]\frac{250}{6}[/tex]
= 41[tex]\frac{4}{6}[/tex]
= 41,66666
≈ 42km/h (rounded to the nearest)
∴ the answer is D.
