Answer» Correct Answer - Option 1 : 11:00 a.m.

Formula:

Speed =Distance/Time

Calculation:

From 6 am, He drives for 2 hourswith a constant speed of 50km/h,

So distance covered = speed × time =50 × 2 =100km.

The time is now8 am, He increases his speed and drives with a speed of 60km/h to cover the remaining distance(280 - 100) = 180km

So time taken = distance/speed = 180/60= 3 hour.

Initially, drives for2 hours then again for 3 hours,

Total 5 hours, from 6:a.m.

Thereforeat 11 am he will reach Ahmedabad.
