Answer:
Step-by-step explanation:
Lines MR and PQ are parallel. Continue the line MR up to the intersection with the line NQ. Denote the point of their intersection as A.
Consider triangle AMN. In this triangle,
- given;
- angles RMN and NMA are supplementary angles;
So, (as the sum of all interior angles add up to 180°)
Angles NAM and MAQ are supplementary angles, then
Angles MAQ and AQP are alternate interior angles, so they are congruant and
Answer:
The speed of plane in still air is 330 kmph
Step-by-step explanation:
Given as :
The distance cover against the wind = 600 km
The time taken against the wind = 2 hours
The distance cover with the wind = 600 km
The time taken with the wind = ( 1 + ) hours
= hours
Let The speed against the wind = x - y kmph
The speed with the wind = x + y kmph
where x is the speed of plane in still air
And y is the speed of wind
So , Speed =
Or, x - y = = 300 ......A
And x + y =
Or , x + y = 360 .......B
From eq A and B
( x + y ) - ( x - y ) = 360 - 300
Or, 2 y = 60
∴ y = = 30 kmph
And x = 360 - 30 = 330 kmph
Hence The speed of plane in still air is 330 kmph Answer
