To get from his house to school, Brandon travels on one street for 2900 meters. He then turns and travels on another street for 3739 meters. This route is represented by the sequence of points in a triangle PQR. According to this, what is the distance, to the nearest meter, from Brandon's house to school represented by the hypotenuse P to R in the triangle?

Two motorcycles start at the same point. One motorcycle travels 15km due north and stops. The second motorcycle travels 32km due west and stops. Which value is closest to the distance between the motorcycles when they stop?

2)Kira is participating in a cycle-a-thon to raise money for cancer research. The course that has been set up for participants to travel is in the shape of a triangle. Two of the angles of the course are 113 and 47, and the length of the side between these two angles is 4.1 km. For each kilometre that Kira cycles, she will raise $14.70 for cancer research. Determine how much money Kira raises if she cycles the course 3 times.
