Question

If Scoobie could drive a Jetson's flying car at a constant speed of 340.0 km/hr across oceans and space, approximately how long would Scoobie take to drive around Earth's equator in days? Use 6200 km for the radius of the Earth.

Answer 1

First step: consider Earth a sphere, and the equator as a chord that runs around it. Second step, determine the circumference of the Earth at the equator, given that 2pi*r=circumference. Plugging in the value 3.14 for pi, and 6200 Km. for the radius: 2*3.14*6200=? You then divide the product by 340 Km/hr to get the amount of time in hours, which must then be divided by 24 hrs/day to get the number of days it takes Scoobie to fly the Jetson car.
