Answer» A can GIVE B a start of 15 seconds in a km race. B takes 4 minutes to run a km. i.e 1000/4= 250 m/min = 250/60 m/sec THEREFORE, B will cover a distance of = 62.5 meters in 15 seconds. The start that A can give B in a km race therefore, is 62.5 meters, the distance that B run in 15 seconds. Hence in a 2 km race, A can give B a start of 62.5 * 2 = 125 m or 30 seconds. A can give B a start of 15 seconds in a km race. B takes 4 minutes to run a km. i.e 1000/4= 250 m/min = 250/60 m/sec Therefore, B will cover a distance of = 62.5 meters in 15 seconds. The start that A can give B in a km race therefore, is 62.5 meters, the distance that B run in 15 seconds. Hence in a 2 km race, A can give B a start of 62.5 * 2 = 125 m or 30 seconds. |
