The scale on a map is 1 cm:60 km. Which of the following proportions could be used to find how many kilometers are represented by 2.5 centimeters on the map?

1cm/60km = 2.5 cm/x km
1cm/60km = x cm/2.5 km
1cm/60km = 2.5cm/ x cm
1cm/60km = x km/ 2.5cm

the first one, because it is also cm to km, and you know that the number of cm is not x, but 2.5
