For a track meet, tara ran the 1,600 m event at constant speed in 5 minutes and 20 seconds. what was her speed? this is 60 points.

300 meters/ minute

5 meters / second

Step-by-step explanation:

Speed is distance divided by time

time = 5 minutes 20 seconds

Changing this to minutes only

20seconds = 20second * 1 minute/60 seconds = 1/3 minute

5 minutes 20 seconds = 5 1/3 minutes

Changing this to an improper fraction

(3*5 +1)/3 = 16/3

speed = 1600 meters / (16/3 minutes)

Copy dot flip

speed = 1600 meters * 3/16 minutes

          = 300 meters/ minute

If we want it in seconds

300 meters/ minute * 1 minute /60 seconds = 5 meters/ second

Work Shown:

5 minutes, 20 seconds = 5*60 + 20 = 300+20 = 320 seconds

Tara runs 1600 meters in 320 seconds, so her speed is 1600/320 = 5 meters per second

The formula I used is

r = d/t

where

r = rate (aka speed)

d = distance

t = time
