Anna left for the city A from city B at 5.20 a.m. She travelled at the speed of 80 kmph for hours 15 min. After that the speed was reduced to 60 kmph. If the distance between the two cities is 350 km, at what time did Anna reach City A?
Option
1) 9.20 am
2) 9.25 am
3) 9.35 am
4) 10.05 am
5) None of these

• 5) None of these
  
  Distance traveled with speed of 80 kmph= (1/4)80= 20 km.
  Remaining distance=350-20=330 km.
  Time taken to travel 330 km @60 kmph= 330/60 =33/6=5 1/2 hours.
  Total time of the journey= (1/4)+(33/6)=69/12 =5 3/4 Hr.=5 Hrs 45 min.
  Anna will reach to city A at time=5:20+5:45=11:05 a.m.

• Distance traveled with speed of 80 kmph= 80+1/4*80=100km
  distance left =350-100=250km
  time taken to cover 250km with speed of 60km/hr=4hr 10min
  there total time taken to reach city A= 5.20+1.15+4.10=10.45am
