Question

If Scoobie could drive a Jetson's flying car at a constant speed of 160.0 km/hr across oceans and space, approximately how long would Scoobie take to drive around Earth's equator in days

Answer 1

Your first step is to find the circumference of the earth, with the numbers given. You can do that by putting the radius of 6200 kilometres into the 2πr equation. That should get you a circumference of 12400π, or about 38,955.75 kilometres.

Next, you can use the rate the Jetson's car is going (180km/h) and divide the 38,955.75 by it to see how many hours it would take at that constant speed.

38,955.75 / 180 = 216.42 hours

Then you can divide that by 24 to get how many days
