The Singhabad express takes time till 8 pm= 12 to 8 pm= 8 hr.
similarily deccan takes to overtake singhbad=2 to 8 pm=6 hr.
so the speed are in the ratio 3:4 hence it will be 30 and 40 km/hr respectively. since the sum is 70.
so average speed=total distance covered by both train/ total time
=(240+240)/(8+6)=34.28 km/hr. ans.
