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 |
- 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.
