c) 4500
d) 4800
Solution:
She leaves Sharjah at 6 pm on Friday and arrives in Dubai the next day. After a 2 hours stopover, she leaves for India at exact noon
=> She reaches Dubai at 10 AM
Dubai is 4 hr ahead of of Sharjah
=> She reaches 6 AM of Sharjah
Hence total 12 hrs journey ( 6 PM to 6AM next day )
2 hrs stoppage
Dubai 2 hours behind India.
Leaves at 12 PM Dubai Means 2 PM India
reaches 1 AM india time
Hence 11 hrs journey
Total Journey time including layover = 12 + 2 + 11 = 25 hrs
While retuning her stopover in Dubai is one hour less Hence
Return journey time = 25 - 1 = 24 hrs including stopover
Total Time = 25 + 24 = 49 hrs
Speed = 180 mph
Distance =49 x 180 = 8820 miles to and fro
distance between Delhi and Sharjah = 8820/2 = 4410 miles
