Answer:

60 km

Explanation:

a) A bearing is an angle, measured clockwise from the north direction.

(They are always given in 3 figures).

Therefore, the bearing of B from A is 090°

b) Method 1

Jafar drives from A to B = 2.4cm

As 1 cm represents 200 km, then 2.4 x 200 = 480 km

Kenzi drives from B to C = 1.2 + 1.5 = 2.7 cm

As 1 cm represents 200 km, then 2.7 x 200 = 540 km

To calculate how much further Kenzi drives that Jafar, subtract the distance Jafar drives from the distance Kenzi drives:

540 - 480 = 60 km

Method 2

The other way to do this is to calculate the difference in distance in centimeters and then convert the answer to kilometres by multiplying it by 200:

Jafar = 2.4 cm

Kenzi = 1.2 + 1.5 = 2.7 cm

Difference = 2.7 - 2.4 = 0.3 cm

Convert to km = 0.3 x 200 = 60 km
