Option B
The equation that represent the minutes you have walked is 600 - 200m = 100
<em><u>Solution:</u></em>
Given that Your school is 600 meters away from your home
Your walking speed is 200 meters per minutes
Therefore,
total distance between school and home = 600 meters
walking speed = 200 meters per minute
Let "m" be the number of minutes you walked
One day you set out from your home and walk to school
After a few minutes, you are 100 meters away from your school
Therefore, remaining distance to be covered = 100 meters
If "m" represents the number of minutes walked, then distance covered in "m" minutes is given as,
distance = speed x time
distance = 200 x m = 200m
So in the total distance of 600 meters, he has covered 200m and remaining distance is 100 meters
From the above statement we can frame a equation as,
total distance - already covered distance = remaining distance
600 - 200m = 100
Thus option B is correct
