Step-by-step explanation:
We can get two equations froms the given info:
x + y = 6.5h Let "x" be first trip time and "y" second trip time.
220x = 280y Relations velocity/time, which gives us distance.
Now, clear x from the 1st eq. x=6.5h-y
And replace x in the 2do eq.
220(6.5h-y) = 280y
1,430h - 220y = 280y
1,430h = 280y + 220y
1,430h = 500y
y = 1,430h/500
y = 2.86h
Now, since x=6.5h-y, x=6.5h-2.86h, x=3.64h
Having the time trip, of x and y:
220x = 280y
220mi/h*3.64h = 280mi/h*2.86h
800.8h = 800.8h
Sum that and we get round trip distance:
800.8h = 800.8h = 1,601.6mi
