Answer:
15 minutes
Step-by-step explanation:
First, the motorcycle goes at a speed of 40 km/hr.
The question asks for how long it would take to travel 10 km.
Well, there are 60 minutes in an hour, since we will be translating into minutes.
Also, 10 km is 1/4 of 40 km, so it would make sense that the time length would be 1/4 of an hour as well.
1/4 of 60 minutes is 15 minutes. So it takes 15 minutes for the motorcycle to travel 10 km.
Now, if all this wordy stuff is too much to comprehend, you can also solve using proportional relationships.
Now cross multiply:
Divide both sides by 40:
Again, this shows that it wouls take 15 minutes for the motorcycle to travel 10 km.

Answer:
1. 2/25
2. 4/15
Step-by-step explanation:
1. P(Y∩X)
Since P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5, this is a conditional probability.
So P(Y∩X) = P(Y)P(X|Y) = 2/5 × 1/5 = 2/25
2. P(Y)· P(X)
P(Y)· P(X) = 2/3 × 2/5 = 4/15
Answer:
The short story have 26 pages
The novel's pages is 364
Step-by-step explanation:
Step one:
given data
let the short story have x pages
so that the novel's pages will be 14x
the combined pages for novel and short story is =390 pages
Required
the individual number of pages
14x+x=390
15x=390
divide both sides by 15
x=26
the short story have 26 pages
the novel's pages will be 14(26)= 364
