During a hike around their native land, participants use a map with a scale of 1: 1,000,000. How long does it take to travel from one city to another on bicycles at a speed of 16 km / h, if the distance between these cities is 0.8 dm on the map?

Let’s convert a numerical scale to a named one.

1: 1000000 means that on the map 1 cm corresponds to 10 km.

Knowing that the distance on the map between cities is 0.8 dm., You can determine this distance on the ground.

Let’s convert 0.8 dm to centimeters.

0.8 dm = 8 cm.

Then let’s make the proportion:

1 cm – 10 km.

8 cm – H.

1/8 = 10 / X.

1 x X = 8 x 10.

X = 80 km.

Knowing the speed of cyclists and the distance, we determine the time it takes for them to cover it.

T = 80/16 = 5 hours.

Answer: Cyclists will need 5 hours.
