Xavier Aptitude Test 2024 Paper

A flight, traveling to a destination $11,200\mathrm{kms}$ away, was supposed to take off at 6:30 AM. Due to bad weather, the departure of the flight got delayed by three hours. The pilot increased the average speed of the airplane by $100\mathrm{km}∕\mathrm{hr}$ from the initially planned average speed, to reduce the overall delay to one hour.
Had the pilot increased the average speed by $350\mathrm{km}∕\mathrm{hr}$ from the initially planned average speed, when would have the flight reached its destination?
