Answer is 36 mins We can approach the problem as followsFirst we have to find the distance we can do so byspeed = 40Time = 45 minshence dt = speed * ttdt = 2 * (15)dt = 30Now the speed can be increased by 10 now the speed is 50tt = dt/speedtt = (30/50) * 60tt = 0.6 * 60tt = 36.0

B) 36 mind=s*ts=40 km/hr=40/60km/mint=45mind=(4/6)*45=30kmnow increased speed= 50 km/hr=50/60 km/mind=30 kmt=d/s = 36 min

Each of the preceding number is multipied by the previous number
So on multiplying 2*2 = 44*2 = 88*4 = 3232*8 = 256256*32 = 8192so the answer for this series is 8192
