lucy walks 2 2/3 kilometers in 1/2 hour. How long will it take her to walk 6 kilometers

Question

Please help solve this and show why

Answer 1

2 and 2/3 = 8/3

the proportion is:

(8/3) 6

------ = -----

(1/2) ?

(8/3) * X = 6 * (1/2)

(8/3) * X = 3

X = 3 * 3/8 = 9/8

It will take her 9/8 hours = 1 and 1/8 hour = 1 hour and 60/8 min

= 1 hour and 30/4 min

= 1 hour and 17/2 min

= 1 hour 8 min 30 seconds
