A treasure map shows 'X marks the spot' 3cm East and 4cm North of a large oak tree. If each cm represents 2 meters, how many meters East and North is the treasure from the oak tree?
- 3m East, 4m North
- 6m East, 8m North
- 4m East, 3m North
- 8m East, 6m North
Show answer
Answer: B. 6m East, 8m North
Each cm is 2 meters. 3cm East is 3 * 2 = 6 meters East. 4cm North is 4 * 2 = 8 meters North.
Describe the location of point P relative to point Q using directions and distance if the coordinates of P are (4, 2) and Q are (1, 0). Assume each unit is 1km
- 3km East, 2km North
- 2km East, 2km North of Q
- 3km West, 2km South of Q
- 2km West, 2km South of Q
Show answer
Answer: A. 3km East, 2km North
P is 4-1 = 3 units East and 2-0 = 2 units North of Q. Since each unit is 1 km, it's 3km East, 2km North.
A surveyor uses a map with a scale of 1:25000 to measure the distance between two points. The distance on the map is 12cm. What is the actual distance in kilometers, rounded to the nearest kilometer?
- 2km
- 3km
- 4km
- 5km
Show answer

A map uses a scale of 1:20,000. Two towns are 15 cm apart on the map. A new map is created with a scale of 1:10,000. How far apart will the same two towns be on the new map?
- 7.5cm
- 30cm
- 15cm
- 20cm
Show answer
Answer: B. 30cm
On the first map, the actual distance is 15cm * 20000 = 300000cm = 3km. On the new map, 300000cm / 10000 = 30cm.
