I would like to give you an example "Pressure Cooker". The pressure level inside the Cooker is increased to 15 PSI(Pounds per square inch). So the rise is cooked at the temperature 120 degree Celsius. Therefore, the rise is cooked in 15 minutes. If you cook the rise in an open vessel, it will take up to 30 minutes to cook the rise. Because the rise is cooked in 100 degree Celsius (because of the normal atmosphere which is less than that inside the Pressure cooker). That's why it takes much time to cook. Similarly, in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100 degree Celsius causing an increase in cooking time.
45) It takes much longer to cook food in the hills than in the plains, because
Answer is:
in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time

Explanation:
At high altitude pressure is less, pressure difference can damage the plane because there will appearer a thrust on plane from high pressure to low pressure. In order to avoid from damage air pressure inside the plane is adjusted by using air pumps.
