प्रश्न
Pradnya exercises regularly by walking along a circular path on a field. If she walks a distance of 3.825 km in 9 rounds of the path, how much does she walk in one round?
उत्तर १
Total distance walked by Pradnya in 9 rounds of the path = 3.825 km
∴ Distance walked by Pradnya in one round of the path = Total distance walked by Pradnya in 9 rounds of the path ÷ 9
= 3.825 km ÷ 9
= `3825/1000 ÷ 9/1`
= `3825/1000 xx 1/9`
= `(3825 xx 9)/(1000 xx 1)`
= `425/1000`
= 0.425 km
Thus, the distance walked by Pradnya in one round is 0.425 km.
उत्तर २
Step 1: Total distance walked in 9 rounds
Pradnya walks a total of 3.825 km in 9 rounds.
Step 2: Distance walked in one round
The distance for one round is:
Distance per round = `("Total distance")/("Number of rounds")`
`=3.825/9`
Step 3: Perform the division
3.825 ÷ 9 = 0.425 km
Pradnya walks 0.425 km in one round.
