Problem with x

[hbtcutie92]

If rain is falling at the rate of 2 inches per hour, how many inches of rain will fall in x minutes??
a)2x b)30/x c) 60/x d) x/ 30.

I don't think its b or d because the question is asking about an hour, not 30 min.

I am not sur if my elimination is correct. I am also unsure if iits a or c.

c) if you have one hour, hoe many inched will fall in minuted in the hour???

a) 2 inches multiplies by the inches fallen in minutes.

Can someone help me? k thanx

60 minutes : 2 inches
1 minute: 2/60 = 1/30 of an inch
x minutes: (1/30) * x = x/30 inches

Have you heard of Dimensional Analysis?

\(\displaystyle \L\,2\,\frac{inch}{hour}*\frac{1 hour}{60 minutes}\)
