2 2/5 in kilometers in 3 3/4 minutes unit rate

Mars2501 [29]

Answer:

Step-by-step explanation:

d = r * t Divide both sides by t

r = d / t

d = distance = 2.25 km

t = time = 3 3/4 minutes = 3.75 minutes

r = 2.25 / 3.75

r = 0.6 km / minute

r = 3/5 km / minute

If the units are different than those given, please state them underneath my answer. I'll get to it as soon as I see your comment.
