Given:
Tangent segment MN = 6
External segment NQ = 4
Secant segment NP =x + 4
To find:
The length of line segment PQ.
Solution:
Property of tangent and secant segment:
If a secant and a tangent intersect outside a circle, then the product of the secant segment and external segment is equal to the product of the tangent segment.
Subtract 16 from both sides.
Divide by 4 on both sides.
The length of line segment PQ is 5 units.
The small plane has the following parameters
Distance = 1200 miles
Speed = 300miles/hour
time = ?
If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours
Considering the distance of the small plane after 6 hours, we have
So the total distance = 1800 miles
Hence the speed of the Boeing 747 will be
The average speed of the Boeing 747 is 900 miles/ hour
