A tortoise, Bernard, starting at point A travels 12 m west and then 150 millimeters (mm) east. How far west of point A is Bernard after completing these two motions? 80m+145cm+7850mm=X mm . What is X ?

1) 11.85 m

2) 89300 mm

Explanation:

1) The tortoise starting from point A travels 12 m west and then 150 millimeters (mm) east.

The distance traveled by the tortoise is the differrence between the distance traveled west and the distance traveled east.

Distance traveled west = 12 m

Distance traveled east = 150 mm

But 1 m = 1000 m, Therefore:

Distance traveled east = 150 mm = 150/1000 m = 0.15 m

Distance west the tortoise is from point A = Distance traveled west - Distance traveled east = 12 - 0.15 = 11.85 m

2) 1 cm = 10 m, 1000 mm = 1 m. Therefore:

X  = 80 m+145 cm+7850 mm = 80000 + 1450 + 7850 = 89300 mm

what are the statements? x
