2/5 of 1/4 of 3/7 of x = 15

2/5×1/4×3/7× = 15

Answer: Option A

Explanation:

ধরি, প্রথম বাইকার অতিক্রম করে = 130 km

∴ দ্বিতীয় বাইকার অতিক্রম করে = 300 - 130 = 170 km

আমরা জানি, t = d/v

এখন ধরি, প্রথমজনের গতিবেগ v1 এবং দ্বিতীয় জনের গতিবেগ v2

∴ সময় একই চলে বলে , d1/v1 = d2/v2

বা = 130/v1 = 170/v2

বা v2/v1 = 170/130 = 17/13

v2:v1 = 17:13
