उत्तर
Devangi travels 50 m distance in 75 steps, then the distance travelled in 375 steps is 0.25 km.
Explanation:
∵ Devangi covers the distance in 75 steps = 50 m
So, she cover the distance on 1 step = `50/75 m`
In 375 steps, she will cover = `50/75 xx 375`
= `18750/75 = 250 m`
= `250/1000 km` ...[∵ 1 km = 1000 m]
= 0.25 km
