How long would it take to drive around Earth's equator?

Question

If you drive your car at a constant speed of 130 km/sec (imagine its possible)

How long would it take to drive around Earth's equator? (Hint: Use Earth's circumference of about 40000 km.) in light-days. Please show how you got to the answer.

I know the answer is 12.8 days but i dont know how to get to that answer.

Answer 1

Leaving aside common sense (e.g. oceans to cross, etc), it would take 40,000/130 hours. I'm not sure where "light-days" come into the picture. That is a measure of distance, not time.

Answer 2

About 2 weeks

Answer 3

the speed must be 130km/h not 130 km/sec

(40000 km)/(130 km/h) = 307.69 hours = (approximately) 12.82 days.

Answer 4

As with your other entry of this question previously, I'm sure you have a typo (whether it's yours or your teacher's).  The speed must be 130 km/hr, not 130 km/s.  There are 3600 seconds in an hour, so divide the 130 km/hr by 3600 to get km/s.  Then divide 40,000 km by your speed in km/s, to get the total number of seconds.

There are 86,400 seconds in a day.  (That's 24 times 3600.)

Answer 5

With or without bathroom breaks?

Answer 6

A really long time because that car is going to have to answer to some water.
