Log boats do not go very far. If the wind is helpful, they travel about 4 km in one hour.

How long will they take to go a distance of 10 km?

4:1::10:x

4*x=10*1

4x=10

x=10/4

x=2.5

Therefore 2 and an half hour is recquired to go a distance of 10km

Distance = 10 km

Speed = 4km / hr

Time = ?

we know that ,

Speed = Distance Traveled / Time Taken

Substituting the values , we get

4 = 10 / T (where T is the Time taken by Boat to Travel distance of 10 km)

or T = 10 /4

or T = 2.5 hours

Hope this helps you!!
