Question

On a map, a measurement of 1.0 cm represents a velocity of 100 m/s. If you were to draw a vector on the map that represents 80 m/s, how long would the vector be?

A. 8.0 cm B. 1.25 cm C. 1.25 mm D. 8.0 mm

Answer 1

Answer:

80 $\frac{m}{s}$ = 8 millimeter

Hence, option D is correct

Explanation:

1 centimeter on map represents 100 $\frac{m}{s}$

10 millimeter on map represents 100 $\frac{m}{s}$.

So, 1 millimeter on map represents 10 $\frac{m}{s}$.

10 $\frac{m}{s}$ = 1 millimeter

Thus,

80 $\frac{m}{s}$ = 8 millimeter

Hence, option D is correct
