Allu is 500/3% as fast as Arjun. Arjun is given a head start of 200 metres. Allu and Arjun completed a race of ______ metre length at the same time.
1). 550
2). 505
3). 500
4). 555
Allu’s speed = 500/3% = 5/3 times Arjun’s.
Let the length of the race be x m.
Let Arjun’s speed be 3s m/s and Allu’s be 5s m/s
According to the question,
⇒ x/5 = (x - 200)/3
⇒ x = 500 metres
