Distance speed problems:

Given:

Josephine walks  1/2 km daily.  

Average speed is 25 meters/minute.

To find:

Time taken by her to complete her exercise.

Step by Step:

1. First find out the distance and time in same units wherever applicable.

  So, change distance from km to meters.

As we know  1km =1000m

\frac{1}{2} km=\frac{1000}{2} meters

=500 meters

2. Write the appropriate formula.

So, s=\frac{d}{t}

where d= total distance travelled

s= average speed

t= total time taken in journey

3. Put the values in formula and get the answer

Calculation:

\frac{500m}{25m/minutes}

=20 minutes

Time taken (in minutes) =   20 minutes

NOTE: The distance used in calculation is 0.5km or 1/2 km.
