2. rate = distance/time

Alden: rate = 2/(3/4) mph
= 2(4/3)
= 8/3 mph or appr 2.67 mph

Kira:
rate = 1.75/.5 mph
= 3.5 mph

9. This was helpful¡ Kira walked at a faster rate.
Alden= 2 miles divided by 3/4 hr. =2 and 2/3

Kira= 1 and 3/4 divided by 30= 7/120 that means that she walked 7 miles in 2 hours since 60 +60=120. And 60 minutes is one hour. You can convert 7/120 to 7/2 = 7 miles in 2 hours. That is an improper fraction so you would have to turn it into a mixed number. 7/2= 3 and 1/2.

2 and 2/3 is less than or < 3 and 1/2 .

So Kira walked at a faster rate.
