i got it right on k12 test plaese rate full star
Find the unit rate for each Olivia and Ryan:
2 2/5 km 15 36 km
------------ * ------- = ------------ = 3.6 km/hr (Olivia)
2/3 hr 15 10 hr
4 1/2 km 2 9 km
------------- * --------- = --------- = 3 km/hr (Ryan)
1 1/2 hr 2 3 hr
Olivia walked 0.6 km/hr faster than did Ryan.
8/x = 2/5
cross multiply
(2)(x) = (8)(5)
2x = 40
x = 40/2
x = 20
now check out ur fractions : 8/20 = 2/5....notice that they are equivalent fractions...just like proportions...nothing but equivalent fractions
