What is the unit rate of 115miles in 2hours

You would divide miles to hours amd get 57.5

115 miles in 2 hours is what we call a rate: a comparison of two numbers with very different units.  This rate is 115 miles / 2 hours.  It's almost like a fraction!  The numerator is 115 miles, and the denominator is 2 hours.

So, what is a unit rate?  A unit rate is a rate (comparison of two numbers) with a denominator of 1.  So we need our rate, 115 miles / 2 hours, to have a denominator of 1.  We need to make the bottom number of our rate 1 hour.  How do we do that?  Well, we need to divide both the numerator (115 miles) and the denominator (2 hours) by 2!

115/2=57.5.  2/2=1.  So, this rate is equal to 57.5 miles / 1 hour.  Since the denominator is 1, THAT's a unit rate!!

57.5 miles / 1 hour

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
