Given:
A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.
Pilot's speed in still air is 315 miles per hour.
To find:
The speed of the wind.
Solution:
Let the speed of wind be x miles per hour.
Speed with wind = 315+x miles per hour
Speed against wind = 315-x miles per hour
We know that,

According to the question,

Divide both sides by 90.

By cross multiplication, we get




Divide both sides by 9.


Therefore, the speed of wind is 35 miles per hour.
Answer:
6(3d+2)
Step-by-step explanation:
Answer: The required probability is 0.3296.
Step-by-step explanation:
Since we have given that
Number of songs = 105
Number of songs are by the Beatles = 10
So, Number of songs are not by the Beatles = 105-10=95
So, the probability that the first Beatles song heard is the fifth song played is given by

Hence, the required probability is 0.3296.
