A company president flew 990 miles in a corporate jet but returned in a smaller plane that could fly only half as fast. If the total travel time was 9 hours, find the speeds of the planes. corporate jet mph smaller plane mph

I'm not completely sure but I think the answer is:

corporate jet 16.5 mph

smaller plane 33 mph

Good luck

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

21/58.
