Final answer:
Following a tire blowout, maintain control of the vehicle, gradually slow down, and then safely pull over. Do not abruptly apply the brakes or attempt to change the tire immediately.
Step-by-step explanation:
If one of your tires blows out, the FIRST thing to do is to keep a firm grip on the steering wheel, maintain your course, and gradually slow down before safely pulling over to the side of the road. It is not recommended to immediately apply the brakes or change the tire, as doing so can cause a loss of control. Instead, you should decelerate by lifting your foot off the gas pedal, allow the car to slow on its own, and use the brakes gently only when the car has slowed down considerably. The provided information related to driving at a specific speed and recording the time taken to stop is not relevant to the correct procedure following a tire blowout.
