What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?

Answers

Answer:

15.75 miles

Step-by-step explanation:

Step one:

given

time= 2.5 hours

speed= 6.3mph

Step two:

Required

Distance

we are given the speed in miles per hour, hence the distance will be in miles

we also know that the expression relating speed, distance and time is given as

speed= distance/time

thus

distance= speed*time

distance= 6.3*2.5

distance= 15.75 miles

By using expression for the speed, distance traveled by me in 2.5 hours will be  

Given in the question,

Speed = 6.3 mphTime for travelling = 2.4 hours

Expression for the speed of an object is given by,

Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

Therefore, Distance = Speed × Time

By substituting the values of speed and the time in the expression,

Distance traveled = 6.3 × 2.5

                              =  15.75 miles

   Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest inch, how many inches are in 16 meters?

Answers

Answer:

629 inches are in 16 meters

Multiply total meters by 100 to get total centimeters:

6 meters x 100 = 600 centimeters.

Now divide total centimeters by 2.554 to get total inches:

600 centimeters / 2.54 = 236.22 inches.

Rounded to the nearest inch = 236 inches.

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.

Answers

Given :

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers  cost $0.05 each.

To Find :

How much would Mrs. Algebra's single order be.

Solution :

Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.

T = $(0.10 + 0.49 + 12.99 + 0.05)

T = $13.63

Therefore, Mrs. Algebra's single order cost is $13.63 .

Hence, this is the required solution.
