A map of Alberta has a scale of 1cm:4 590 000cm. The distance on the map between Edmonton and Calgary is 2 and 3/8 in . What is the actual distance between Edmonton and Calgary, rounded to the nearest kilometer?

Convert 4,590,000cm to kilometers
4,590,000/100 cm/1000 meters=45.9 kilometers
So now, the scale on the map is =1 cm =45.9 km
Convert inches to cm:
1 inch =2.54 cm
2 3/8 inches * 2.54 cm =6.0325 cm - the distance between Calgary and Edmonton on the map.
Every 1 cm on the map =45.9 km on the ground.
So:6.0325 cm on the map * 45.9 km on the ground =276.89175 =~277 km - the ground distance between Calgary and Edmonton.
