Using the relation between velocity, distance and time, it is found that:
- The speed of the wind is of 2 mph.
- The speed of the broom is of 14 mph.
Velocity is <u>distance divided by time</u>, hence:
Flying with the wind, in which the 48-mile trip took 3 hours, hence:
Her flight home against the wind took 4 fours, hence:
Adding the two equations:
Hence:
- The speed of the wind is of 2 mph.
- The speed of the broom is of 14 mph.

I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
: It looks like this in the calculator
× cos A=(0.6489)
( and cos cancels out)
A=(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)

The highlighted sector is exactly 3/4 of the circle area, because is 3/4 of
which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be squared cm.
The remaining sector, of course, is squared cm.
