If a scale of 2cm represents 3/4km, find the length on the scale drawing with an actual length of 30km.
If a scale of 2cm represents 3/4km, find the length on the scale drawing with an actual length of 30km.
If 2cm represent 3/4then what is the answer
To find the length on the scale drawing with an actual length of 30 km:
We can use the proportion:
2 cm / (3/4) km = x cm / 30 km
First, we need to convert 3/4 km to cm:
(3/4) km = (3/4) x 100000 cm/km = 75000 cm
Now we can substitute the values into the proportion:
2 cm / 75000 cm = x cm / 30000 cm
Cross-multiplying:
2 cm x 30000 cm = 75000 cm x x cm
60000 cm = 75000 cm x
x = 60000 cm / 75000 cm
x = 0.8 cm
Therefore, the length on the scale drawing with an actual length of 30 km is 0.8 cm.
We can use the proportion:
2 cm / (3/4) km = x cm / 30 km
First, we need to convert 3/4 km to cm:
(3/4) km = (3/4) x 100000 cm/km = 75000 cm
Now we can substitute the values into the proportion:
2 cm / 75000 cm = x cm / 30000 cm
Cross-multiplying:
2 cm x 30000 cm = 75000 cm x x cm
60000 cm = 75000 cm x
x = 60000 cm / 75000 cm
x = 0.8 cm
Therefore, the length on the scale drawing with an actual length of 30 km is 0.8 cm.
