Estimate how many days it would take to walk around the world, assuming 12 h walking per day at 4 km/h. assume that the oceans are crossed in the same manner as the land. the radius of earth is 6.38 ã 103 km.

836 days

Step-by-step explanation:

Given

radius of earth is

Walking speed 4 km/h

walking 12 hour a day

perimeter of earth is

Time taken

therefore it requires

step-by-step explanation:

ask goog great chance of finding the solution there

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
