Two persons A and B start from the opposite ends of a 450 km straight ...
First person speed = 25 m/s * 18/5 = 90 kmph
Second person speed = 35 m/s * 18/5 = 126 kmph
View all questions of this testTwo persons A and B start from the opposite ends of a 450 km straight ...
Quantity I: First person speed = 25 m/s
Quantity II: Second person speed = 35 m/s
Since they are running to and from between the two ends, the total distance covered by each person is twice the length of the track, which is 2 * 450 km = 900 km = 900,000 m.
Since speed = distance / time, the time taken by each person to cover this distance can be calculated using the formula time = distance / speed.
For the first person:
Time taken = 900,000 m / 25 m/s = 36,000 s = 10 hours (since 1 hour = 3,600 s)
For the second person:
Time taken = 900,000 m / 35 m/s = 25,714.29 s ≈ 7.143 hours
Therefore, Quantity I is greater than Quantity II.
