Question

Every 24 hours, Earth makes a full rotation around its axis. Earth's speed of rotation at the equator is 1,670 km per hour. What is the circumference of Earth's equator?

Answer 1

I'm pretty sure it's 40,075.

Answer 2

the circumference of Earth's equator is 40080 Km

Explanation:

Hello

in this case, you have a time ( 24 hours)it is the time it takes to make a full rotation , and a speed (1670 Km per hour),just apply the equation,

the speed of a object is given by:

`speed=(distance)/(time) \\isolating distance\\speed(v)*time=distance\\d=v*t`

Step 1

put the values into the formula

d=v*t

let

v=1670 km per hour

t=24 hours

`d=v*t=1670 (km)/(hour) * 24 hours\\d=40080 Km`

the circumference of Earth's equator is 40080 Km

Have a great day.
