Marvin walks at a speed of 7 feet per minute. how many miles per hour is this?

or

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed

x ----> the distance

y ----> the time

so

we have

Remember that

so

Find out the speed in miles per hout

Simplify

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
