Question

The scale on a map showing distances between cities is 1 cm = 20 miles. Determine the scale factor between Illinois and Connecticut if it shows 45 cm in the old map and is enlarged by 2 times, then 1 cm = ___ miles.

12
90
10
40

The correct answer is: 90

distances between cities is 1 cm = 20 miles
45 cm = 45 × 2 = 90 cm, ( enlarged by 2 times )
45 × 200 = 900 miles, $fraction numerator 900 blank m i l e s over denominator 90 blank c m end fraction$ = $fraction numerator 900 blank divided by blank 90 over denominator 90 blank divided by blank 90 end fraction$ = $fraction numerator 10 blank m i l e over denominator 1 blank c m end fraction$
