Question

The distance on a map between a student’s house and her job is 4 centimeters. On the same map, the distance between her house and her school is 6 centimeters. The actual distance from her house to school is 9 kilometers. If d represents the approximate distance in kilometers between her house and her job, what is d?
A. 6 km
B. 9 km
C. 12 km
D. 18 km

HURRY i need this fast!!!!!!!!!!!

Answer 1

6cm - 900000cm multiplica cruzado ⇒ 6x = 900000 ⇒  x = 150000cm
1cm - x

1cm - 150000cm multiplica cruzado -> d = 600000cm = 6km  4cm - d

Answer 2

Answer:

Option A is the correct answer.

Step-by-step explanation:

The distance on a map between a student’s house and her job is 4 centimeters. On the same map, the distance between her house and her school is 6 centimeters. The actual distance from her house to school is 9 kilometers.

$\texttt{Scale of map =}\frac{6cm}{9km}=\frac{0.06m}{9000m}=\frac{1}{150000}$

Now we need to find approximate distance in kilometers between her house and her job, d

Distance in map = 4 cm

                    d = 4 x 150000 cm = 600000 cm = 6000 m = 6 km

Option A is the correct answer.
