Answer:
Step-by-step explanation: To find the equation of the perpendicular line, take the reciprocal of the slope with the opposite sign.
For example, the reciprocal of 4/3 is 3/4 and if it's negative, the opposite is positive.
The reciprocal of 2 is 1/2. and if it's positive, the opposite is negative.
The reciprocal of any number or fraction is whatever you multiply it by to get 1. 4 times 1/4 is 1 5/4 times 4/5 is 1. What about 1 ? 1 times 1 is 1. So one is its own reciprocal!

Answer: option B and D (1000m/km and minute/60 second)
In this question, we have two unit that needed to be converted, kilometer/minutes into meter/second.
First, we need to convert km into the meter. One kilometer is equal to 1000 meter. To change kilometer into the meter, the unit used for multiplication should be 1000m/km which is option B.
Then we need to convert minute into the second. One minute is equal to 60 seconds. To change "/minute" into "/second" the multiplication unit should be minute/60 second which was option D
