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
