Question

Ana drives at a speed of 175m/s. she recorded a distance of 2km. Find the time.

Answer 1

The time it took her to drive 2 km is 11.43 seconds, because sonverting kilometers to meters, it is 1000 meters to every kilometer, and she travels 2 kilometers, which is two-thousand meters. Then to find the time you need to divide the time by the speed, and with that you get 11.4285714286, or 11.43 seconds.

Answer 2

Answer:

11.4  s

Explanation:

The relation among distance (d), speed (s), and time (t) is

d = st                  Divide both sides by s and transpose

t = d/s

d = 2 km = 2000 m

s = 175 m/s         Calculate t

t = 2000/175

t = 11.4 s
