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

Answer:

the circumference of Earth's equator is 40080 Km

Step-by-step 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:

$speed=\frac{distance}{time} \\isolating distance\\speed(v)*time=distance\\d=v*t$

Step 1

put the values into the formula

d=v*t

let

v=1670 km per hour

t=24 hours

$d=v*t=1670 \frac{km}{hour} * 24 hours\\d=40080 Km$

the circumference of Earth's equator is 40080 Km

Have a great day.

Answer 2

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