Given: A scale used on a map is 1:900,000.The distance on the map between two cities is 3cm
To find : how far apart are the cities
Solution:
A scale used on a map is 1:900,000
=> 1 cm on map = 900,000 cm in actual
100 cm = 1 m
=> 1 cm on map = 9000 m in actual
1000 m = 1 km
=> 1 cm on map = 9 km in actual
=> 3 cm on map = 3 * 9 = 27 km in actual
Distance = 27 km
Speed = 90 km/hr
Time = Distance / Speed
=> Time = 27/90
=> Time = 3/10 hr
= 18 mins
it will take 18 mins to drive from one to the other at 90km/hr
