Cars Y and Z travel side by side at the same rate of speed along parallel roads as shown above. When car Y reaches point P, it forks to the left at angle x, changes speed and continues to stay even with car Z as shown by the dotted line. The speed of car Y beyond point P is what percent of the speed of car Z?

1) The speed of car Z is 50 miles per hour

2) x=45

B for me.

If the speed of car z is s mph then, speed of car y will be x/sqrt2 mph and percentage can be found out.

no, I just got the books from a friend that took the course. My friend ended up getting 730, but he was scoring pretty high before the course

You are right. Stmt2 gives one of the angles as 45 degree and since this is a right angled triangle, it will be an isosceles triangle.
