It took the high school hockey team 5h to travel to a tournament in Thunder Bay. They travelled by bus and plane a total distance of 1320km. If the bus averaged 40km/h and the plane averaged 600km/h, determine the time they spent travelling by plane.

Answer:It took 2 hours by planeStep-by-step explanation:let bus is represented by x and plane is represented by ythe total distance of bus and plane will be represented by equation:40 x + 600 y = 1320           (1)the total time taken by bus and plane will be represented by:x + y = 5                              (2)solving equations (1) and (2) simultaneously:Multiply by 40 on both sides in eq (2)  and then subtract (1) and (2)40 x + 600 y = 132040 x + 40 y = 200_______________           560 y = 1120                 y   = 1120/ 56                 y= 2since plane is represented by y so, the time they spent travelling by plane is 2 hours.
