Gaurav takes 15 rounds of a rectangular park whose length is twice its breadth. If the total distance covered by Gaurav is 900m
Dvinal [7]

Answer:

length = 20 breadth = 10

Step-by-step explanation:

divide 900 by 15

= 60

60 divided by 6 because the length is twice the breath

60 / 6 is 10

so ten is the breadth of one side and double that is 20 so the length is 20

Hope this helped!

The formula for volume always involves three dimensions.  

In this case, the volume of a cube is V=s^3, where s is the side length of the cube.

To solve for that side length, you'd need to use a cube root.

Rosa can run 4 miles in 56 minutes.How many miles does rosa run if she runs 42 minutes?
Alex Ar [27]
Rosa runs 3 miles in 42 minutes.

I divided 42 by 56 to get the percentage that will be multiplied to 4 miles to get the number of miles Rosa runs in 42 minutes.

42 / 56 = 0.75 * 100% = 75%

75% * 4 miles = 3 miles.

3 miles within 42 minutes
