1. A grand tour of four cities begins at city A and makes successive stops at cities B, C,
vampirchik [111]

Using <u>distance between two points</u>, it is found that the total distance covered on the tour is of 3400 miles.

Given two points (x_1,y_1) and (x_2,y_2), their distance is given by:

D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

In this problem, the formula is used to find the distance covered on each tour, hence:

d_{AB} = \sqrt{(400 - 0)^2 + (300 - 0)^2} = 500

d_{BC} = \sqrt{(-800 - 400)^2 + (800 - 300)^2} = 1300

d_{CD} = \sqrt{(-800 - (-800))^2 + (0 - 800)^2} = 800

d_{DA} = \sqrt{(0 - (-800))^2 + (0 - 0)^2} = 800

Then, the total <em>distance </em>is given by the sum of each separate distance, hence:

d = d_{AB} + d_{BC} + d_{CD} + d_{DA} = 500 + 1300 + 800 + 800 = 3400

The total distance covered on the tour is of 3400 miles.

Rick and Ben had the same amount of money. Ben spent $138. In the end,Rick had 4 times as much as Ben.How much did Rick have?
Elena-2011 [213]
At the start, Ben and Rick have the same amount of money.  Let x represent that amount.

Rick's money:  x
Ben's money:  x

Then, Ben spends $138.

Rick's money:  x
Ben's money:  x - 138

At that point, Rick has 4 times the amount that Ben has.

x = 4(x - 138)
x = 4x - 552
552 = 3x
184 = x

Rick has $184.
