Question

A walking trail is 1 km long . Cecilia has walked the first 20 m . How much further can she walk on the trail ?

Answer 1

1 kilometer is 1000 meters

Cecilia has walked 20 meters

The distance remaining is 1000 - 20 = 980 meters.

Answer 2

A walking trail is 1 km long . Cecilia has walked the first 20 m .

We know 1 km = 1000m

Cecilia has walked the first 20 m.

Walking trail is 1 km so its 1000m.

Already walked 20m so we subtract 20 from 1000

1000 - 20 = 980 m

To convert 980 m into km we divide by 1000

$\frac{980}{1000} = 0.98 km$

She has to walk 0.98 km further on the trail
