Question

Walking at an average speed of 3.5km/h, it takes David 0.25h to get to school. What distance does David walk to get to school?

its a science physics question...

Answer 1

25/60 = .416  this is the decimal equivilent of the time it takes him to walk home. Multiply .416 x 3.5 and you come up with 1.456km.

Answer 2

find out how many feet in a mile

then how many feet in a kilometer

divide ft in a mile by ft in a kilometer

multiply that answer by 3.5 to get mph

.25hrs is 1/4 of an hour so divide the mph answer by 4 and there is the distance he travels without using the stupid metric system the  Edit: jerry p's answer is not it

Answer 3

distance = rate * time

d = r * t

d = 0.25h * 3.5 km/h

d = 0.875km
