I think it’s questions 1 and 2
Step-by-step explanation:
I dont know if this helps but that what I came up with
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is

total distance of other way is

now, we can that distance is same from both sides
so, we get

now, we can solve for t



now, we can find one way distance

Good day ~_~ /////////////
The dividend is the number being divided so the dividend is 27,438
The divisor is the one dividing the number so the divisor is 9
The quotient is your answer so you quotient is 3048
Your answer is C.
