a bagel cost $0.80.On Wednesday ,a dozen bagels cost $6.00. what is the unit price of a bagel on wednsday, if you buy 3 bagels?
maria [59]

If a bagel costs $0.80 any day, then the unit price
is $0.80 per bagel.

If the unit price of a bagel is $0.80 , then every bagel
you buy costs $0.80 .

Only one thing changes:  The price of a dozen on Wednesday.

If you buy 1 dozen ... or any number of dozens ... on Wednesday,
then the unit price of the contents of that bag is

                        ($6.00) / (1 dozen)  =  $6.00 per dozen

If you want to convert that to a
different unit of measure, then
you do it like this:

                 (6.00  $/dozen) x (1 dozen/12 bagels)

             =  (6.00 x 1 / 12)  ($/bagel)

             =        0.5  $/bagel

                 or   $0.50 / bagel .

Two trains move between two towns. It takes the first train 2 hr 48 min and it takes the second 4 hr 40 min. The rate of the fir
Umnica [9.8K]

Answer:

182 miles.

Step-by-step explanation:

Given:

Two trains move between two towns.

Time taken by first train = 2 hr 48 minutes =

Change minute into hour:

60 minute = 1 hour

1 minute = \frac{1}{60}

48 minutes = \frac{1}{60}\times48=\frac{48}{60} =0.8\ hour

Time taken by first train in hour = 2+0.8=2.8\ hours

Time taken by second train =  4 hr 40 minutes

Similarly, 40 minutes = \frac{40}{60} =0.67\ hour

Time taken by second train in hour = 4+0.67=4.67\ hours

The rate of the first train is 26 mph more than that of the second train.

Question asked:

What is the distance between these towns ?

Solution:

Let speed of second train = x\ miles\ per\  hour

<u>As the speed of the first train is 26 mph more than that of the second train. </u>

Speed of first train = 26+x\ miles\ per\ hour

As two trains move between two towns means distance traveled by both train is same.

By using : Distance=speed\times time

Distance traveled by first train = Distance traveled by second train

speed\times time =

(26+x)2.8=x\times4.67

26\times2.8+x\times2.8=4.67x\\72.8+2.8x=4.67x\\

Subtracting both sides by 2.8x

72.8=1.87x

Dividing both sides by 1.87

x=38.93

Speed of second train = 38.93 miles per hour

Distance=speed\times time

              = 38.93 \times 4.67

              = 181.80 miles.

Thus, the distance between these towns is 182 miles (nearest whole number).
