The scale of a map is 1 : 100,000. The distance between two houses on the map is 3.2 cm. Find the actual distance, in kilometers, between the two houses?

The actual distance between the two houses is:

3.2 km

Step-by-step explanation:

Proportions:

1cm       ⇔  100000 cm

3.2 cm  ⇔  W cm

W = 3.2*100000/1

W = 320000 cm

1 km = 100000 cm

320000cm = 320000/100000 = 3.2km

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
