Answer:

65.8 miles per hour

Step-by-step explanation:

Given : A tractor-trailer travels 205.296 miles in 3.12 hours.

To Find:What is the speed at which the tractor-trailer is traveling

Solution:

Distance traveled = 205.296 miles

Time taken = 3.12 hours.

So, Speed = \frac{Distance}{time}

So, Speed = \frac{205.296}{3.12}

Speed = 65.8

Hence the speed at which the tractor-trailer is traveling is 65.8 miles per hour

So, Option D is correct.

vazorg [7]

Answer:

2:3 unless it wants it in total, then 220:330

Step-by-step explanation:

it gives you the answer with the fraction.  A ratio is basically saying with x:y for every x number of one thing there are y number of another.  In this case we know 2/5 will be green, so how many will be red?  3/5.  So for every 2 greens there are 3 reds.

Another way of looking at it is for the totals.  there are 550 total, so 2/5 of that is green.  2/5 of 550 is 220, while 3/5 is 330  so that means of the 550, the ratio is 220:330.  Kinda like simplifying fractions where 220/550 is the same thing as 2/5

What is the difference between a rate and a unit rate? Show an example
QveST [7]

Answer:

Rate: In mathematics, a rate is the ratio between two related quantities in different units. If the denominator of the ratio is expressed as a single unit of one of these quantities. "The most common type of rate is "per unit of time."

Unit Rate: A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
