The distance between two cities on a map is 3.5 centimeters. the map uses a scale in which 1 centimeter represents 20 kilometers. what is the actual distance between these two cities in kilometers?

If the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. The actual distance between these two cities in kilometers will be 70 kilometers

Using this formula

Actual distance=Distance×Kilometers

Where:

Distance=3.5 centimeters

Kilometers=20 kilometers

Let plug in the formula

Actual distance=3.5 centimeters×20 kilometers

Actual distance=70 kilometers

Inconclusion If the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. The actual distance between these two cities in kilometers will be 70 kilometers

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
