Answer:
A
Step-by-step explanation:
AA stands for angle angle.
For the two triangles given being similar by AA, they should have two equal angles. Of course, once two angles are equal the third one will be equal as well, once the angles of a triangle always add up to 180º.
Therefore, the angle ∠NMO and ∠QPR should be equal.
Given,
Time taken by motorboat to going 200 miles upstream is 5 hours.
Time taken by motorboat to going 200 miles downstream is 4 hours.
At upstream,
The speed of boat is offosed by the speed of current.
At downstream,
The speed of boat is incraesed by the speed of current.
Consider,
The speed of boat is b.
The speed of current is c.
The speed is calculated as,
Similarly,
Substituting the value of b from equation (2) then,
Substituting the value of c in equation (1) then,
Hence, the speed of boat is 45 mile per hour and speed of current is 5 mile per hour.
