Probability 1st song is sung by female : 55/100 reduces to 11/20
probability 2nd song is sung by a male : 35/100 reduces to 7/20
probability 3rd song is instrumental : 10/100 reduces to 1/10
probability of all 3 events happening : 11/20 * 7/20 * 1/10 = 77/4000
The average speed of Joshua during that time is 2500 m/h.
Explanation:
It is given that Joshua started cycling at 5:15 pm. By 8:09 pm he has covered a distance of 7250 m.
The total time taken by Joshua from 5:15 pm to 8:09 pm is

Dividing we get,

Adding, we have,

Thus, the total time taken by Joshua is 
To determine the average speed we use the formula,

where
and 
Hence, substituting the values we have,

Dividing, we get,

Thus, the average speed of Joshua during that time is 2500 m/h.
I think Point A and B are 2 inches apart or all of them is right
