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

mote1985 [20]

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).

Trilobites to concert tickets from her friend she pays $90 for the two tickets she looks at the tickets and see that each ticket

Setler79 [48]

Answer:

Her friend gave Sheila a markdown of $15.

Step-by-step explanation:

Given;

Amount paid for 2 tickets = $90

Actual amount for each ticket = $52.50

we need to find the markdown value did her friend gave to Shelia.

Solution:

each ticket = $52.50

2 tickets = Cost of 2 tickets.

By using unitary method we get;

Cost of 2 tickets = $52.50\times 2 =\$105.00$

Now To find the markdown we will subtract the Amount paid for 2 tickets from the actual Amount of 2 tickets.

framing in equation form we get;

Markdown $105-90 =\$15$

Hence her friend gave sheila a markdown of $15.
