A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?

mina [271]

Answer:

33.75 miles in 45 minutes,

45 miles in an hour

Step-by-step explanation:

45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,

1 3/4= 7/4 ---> 7/4*3=5.25

car travels 5.25 miles for every 7 minutes,

45/7*5.25= 33.75 miles

1 hour (60 minutes):

using that the car travels 5.25 miles for every 7 minutes,

60/7*5.25= 45 miles

Hope that makes sense!

Answer: $V=234\ yd^3$

Step-by-step explanation:

By definition, the volume of a rectangular prism can be calculated with the following formula:

$V=lwh$

Where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.

In this case, you can identify that the length, the width and the height of this rectangular prism given in the exercise, are:

$l=13\ yd\\\\w=6\ yd\\\\h=3\ yd$

Then, knowing its dimensions, you can substitute them into the formula:

$V=(13\ yd)(6\ yd)(3\ yd)$

Finally, evaluating, you get that the volume of that rectangular prism is:

$V=234\ yd^3$
