The speed of paul is 45 km/h
Explanation:
Let they meet at point T after time t. Let the speed of B = x kmph
Consider the distance AT. It was covered by paul in 6 hours and peter in t hours.
Hence ,
6x = 30t..........................eq1
Consider the distance BT. It was covered by paul in t hours and peter in 13.5 hours.
Hence,
13.5 * 30 = xt ..................eq2
Dividing eq1 by eq2 we get;
6x/13.5*30 = 30t/xt
=> 6x/13.5*30 = 30/x
=> x² = 13.5*30*30/6 = 2025
=> x = 45 km/h
Hence the speed of paul is 45 km/h
