Jonah drove the first half of a 200-mile trip in x hours and the second half in y hours. Which of the following is equal to Jonah’s average speed, in miles per hour, for the entire trip?	Choose the correct choice from the following:
A) 100/(x + y)  B) 200/(x + y)  C) 25/x + 25/y  D) 50/x + 50/y  E) 100/x + 100/y
Time taken by Jonah to cover first half i.e 100 miles of a 200 mile trip = x   time taken by Jonah to cover the second half i.e 100 miles of a 200 mile trip = y   Total time taken by Jonah = x+y   Jonah's average speed for the entire trip =total distance /total time   =200/(x+y)   Answer 200/(x + y)
