Let x be the average airspeed of the plane. Let y be the average wind speed. Initial trip: 18 = (x + y) Return trip: 18 = (x – y) Dalia had an average airspeed of miles per hour. The average wind speed was miles per hour.

what level of math? also i don't need to be paid if i can you.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

answer is c

step-by-step explanation:

81/12=324/x

x=48
