Answer 1

Unit walking rate in miles per hour = 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.


Unit walking rate in hours per mile
 
8/17 hours per mile.

Since it's my name I had to answer xD

Answer 2

Answer:

Rachel walked 2 ⅛ miles per hour

Rachel used 8/17 hour per mile

Step-by-step explanation:

Working with two units time and distance, where time is in hours and distance is in miles.

Given that she walked 5 2/3 miles in 2 2/3 hours.

Distance covered while she walked = 5⅔ = 17/3 miles

Time taken = 2⅔ = 8/3 hours

To find Rachel's unit walking rate in miles per hour simply implies that, distance Rachael cover in one hour. We will be

Distance covered/time taken = 17/3 ÷ 8/3

= 17/3 x 3/8

= 17/8 = 2 ⅛

i.e Rachel walked 2 ⅛ miles per hour

To find Rachel's unit walking rate in hour per mile simply implies that time in hour used by Rachael to walk one mile. This will be

time taken/distance covered = 8/3 ÷ 17/3

= 8/3 x 3/17

= 8/17

i.e Rachel used 8/17 hour per mile
