It is 16,700 meters to cycle there and back
The answer would be 7 miles. I can see that the initial charge is $35. For every mile there is a $2 fee. I found this by looking at how much the fee increases from 1 mile to 3 miles. There’s a $4 increase. So $4 divided by 2 miles is equal to 2. 1 mile is equal to $2 after the initial price. I counted by 2s from 41 to 49. Every count of 2 is a mile. When I landed on 49 I was at the 7th mile. A half of a mile is equal to $1. I know this because from 7 miles to 8.5 miles, there is a $3 increase. The 8th mile would be $51, but the half of a mile increases the cost by $1. Sorry if it’s very wordy. The answer is 7 miles though!
The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9 
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30
Thus the area of the square increasing at 30

One revolution also corresponds to an angular displacement of 2π rad.
So, the angular velocity is
120 rev/min = (120 rev/min) * (2π rad/rev) = 240π rad/min
