Refer to the data below and answer the questions that follow.
The variation in the speed of a car on a particular day at the respective times is shown in the table below:

s(km/hr)	0	40	50	85	10	10
t(hr)	11.00 am	11.30 am	1.00 pm	1.30 pm	3.30 pm	4.30 pm

9If car maintains the speed it has at 4.30 p.m. then at what time will the car cover the same distance as it had covered from 11.00 a.m. to 1.00 p.m.?

Option : D
Explanation : Distance covered are the same.
Speed in the latter is maintained at 10 kmph.
∴ 77.5 = 10 × x
=> x= 7.75 hours.
Hence, clock time will be 4.30 + 7 hours 45 mins
= 12.15 a.m.
