Signs of Lyme disease include skin rash and painful inflammation of joints (particularly the knees), accompanied by flu-like symptoms. The symptoms of Lyme disease increase in severity as the disease spreads though the body. Early diagnosis and treatment are important to stop the progression of the disease. If untreated, the disease can result in neurological disorders such as peripheral neuropathy, including Bellâs palsy, as well as pain, numbness or weakness in the limbs.

Let's first assume the wind is a tailwind blowing in the same direction as the aircraft as it moves down the runway. We can now solve for the plane's airspeed using the relationship: Since the tailwind subtracts from the ground speed of 180 mph, the plane's airspeed is only 155 mph (250 km/h). This speed is insufficient to lift off, so the plane needs a longer runway to make up that extra 25 mph and generate the lift needed to takeoff.
