In which s is the velocity.
It takes 63 min to travel 70 mi.
So i am going to find the velocity in miles per minute
how many hours would it take to travel 180 mi?
I am first going to find the time in minutes, then divide by 60 to pass to hours.
It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.
Lets assume center point of circle as O
OD is the radius of circle . so OD is also 7
All the sides of the triangle are equal . so angle at the center O is 60 degree.
radius = 7
Length of arc CD =
