Solution
If the distance travelled by a rickshaw in one hour is 10 km, then the distance travelled by the same rickshaw with the same speed in one minute is `underlinebb(500/3 m)`.
Explanation:
The distance travelled by a rickshaw in 1h = 10 km
In 1 min, rickshaw covered the distance = `10/60` km
= `(10 xx 1000)/60` m ...[∵ 1 h = 60 min and 1 km = 1000 m]
= `1000/6`
= `500/3` m
Hence, `500/3` m
