# Distance and direction

Navigation requires distance and direction. Direction is usually given using three-figure bearings.

### Example

A boat leaves harbour to sail around a nearby island. The journey is split into four legs (parts).

The first two legs are given in the table.

BearingDistance
1st leg$063^{o}$$5.3km$
2nd leg$105^{o}$$7.0km$
3rd leg
4th leg

To complete the table, first draw a scale diagram.

### Step one

Show the first two legs of the journey on the diagram.

### Step two

Draw the 3rd and 4th legs on the diagram so that the ship travels to the point marked X and then on to the harbour.

### Part three

Complete the table for these two legs showing the bearings and distance.

BearingDistance
1st leg$063^{o}$$5.3km$
2nd leg$105^{o}$$7.0km$
3rd leg$238^{o}$$5.9km$
4th leg$293^{o}$$6.8km$
