Question

Lin ran 2 3/4 miles in 2/5 of an hour. Noah ran 8 2/3 miles in 4/3 of an hour. Who ran first Lin or Noah?

Answer 1

We cannot tell who ran FIRST

But we CAN figure out who is FASTER !!!

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???
