Time taken to cover the distance
and 
We know that,




It is given that,

therefore,

Speed Of plane in Kilometers per hours 

Speed of in miles per hour is
and Speed in kilometer per hour 
SOLUTION:
A normal distribution would model this situation because the distribution is approximately symmetrical, thus the mean, median and mode are approximately the same and the population size is large ( greater than 30).
