Lin ran 234 miles in 25 of an hour. Noah ran 823 miles in 43 of an hour. Who ran faster, Noah or Lin?

How far would Lin run in 1 hour?

How far did Noah run in 1 hour?

How long would it take Lin to run 1 mile at that rate?

How long would it take Noah to run 1 mile at that rate?

LIN

(2 and 3/4) divided by 2/5 =

11/4 divided by 2/5 =

11/4 * 5/2 = 55/8 miles per hour

             = 6 and 7/8 mph

NOAH

 (8 and 2/3) divided by 4/3 =

26/3 divided by 4/3 =

26/3 * 3/4 =

 26/4 = 13/2 = 6 and 1/2 mph

So it comes down to 7/8 vs 1/2

COmmon denominator is 8.

1/2 = 4/8

So     0.875 = 7/8 > 4/8=1/2 = 0.5

So who's faster???

Step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
