Answer:
1.2 km/min
Step-by-step explanation:
ROC? rate of change? if not rate of change than my answer may not be correct
24km/20min = 1.2 km/min

Answer:
Sorry but i cannot understand your question !!
Step 1
find the length of a circumference
L=2*pi*r-------------> 2*pi*26.9=53.8*pi m
Step 2
find <span>the arc length
</span>if 2*pi radians --------------> 53.8*pi m
(9/5)*pi radians------------> X
X=[(9/5)*pi*53.8*pi]/[2*pi]-------------> [9*53.8*pi]/[5*2]=152.04 m
the answer is 152.04 m
