William runs 5 meters in 20 steps. how many kilometers will he run after taking 1,000 steps?

kilometer=1,000 meters

5m=20steps
x m=1000steps

    5m             x m
=
20 steps    1000steps

cross multiply
20x=5000
x=250m

So now we have to convert 250m to km

1000m=1km
250m= x km

 1000m      250m
=
   1 km       x km

Cross multiply
1000x=250
divide both sides by 1000
x=0.250km

Answer=0.250 km

5 meters divided by 20 steps=0.25 meters per step
0.25meters times 1000 steps=250 meters per 1000 steps
Willam will run 250 meters
