It took the high school hockey team 5h to travel to a tournament in Thunder Bay. They travelled by bus and plane a total distanc e of 1320km. If the bus averaged 40km/h and the plane averaged 600km/h, determine the time they spent travelling by plane. (please explain i know the answer is 2 but how?)
1 answer:
Entire distance = 1,320 Entire time = 5 hours bus avg = 40 km/h plane avg = 600 km/h Working this by trial and error 1 hour bus 4 hour plane = 40 + 2,400 = 2,800 distance (too high) 2 hour bus 3 hour plane = 80 + 1,800 = 1,880 distance (too high) 3 hour bus 2 hour plane = 120 + 1,200 = 1,320 distance (Correct!!) So, they traveled 3 hours by bus and 2 hours by plane (yes, you had the right answer).

Answer: $1090
Step-by-step explanation:
Since Caroline won $205000 in a lottery and then paid $96000 in taxes, the remaining amount will be:
= $205000 - $96000
= $109000
The interest that the account will earn after just 6 months will be:
Interest = PRT
= 109000 × 2% × 6/12
= 109000 × 0.02 × 0.5
= $1090
