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

80
`(m)/(s)` = 8 millimeter

Hence, option D is correct

Step-by-step explanation:

1 centimeter on map represents 100
`(m)/(s)`

10 millimeter on map represents 100
`(m)/(s)`.

So, 1 millimeter on map represents 10
`(m)/(s)`.

10
`(m)/(s)` = 1 millimeter

Thus,

80
`(m)/(s)` = 8 millimeter

Hence, option D is correct
