Answer:
11. 8 mph
12. Yes the rates are equivalent
Explanation:
11.
We need to calculate the distance the person would walk in 1 hour.
To do this, multiply both by 24:
1/3 x 24 = 8 miles
1/24 x 24 = 1 hour
Therefore, the person's speed = 8 mph
12.
0.2 km for every 0.5 min
0.8 km for every 2 min
If we multiply both numbers in the first rate by 4 we will get:
(0.2 x 4) km for every (0.5 x 4) min = 8 km for every 2 min
This is the same as the second rate.
Therefore the rates are equivalent (as they are the same)
