Question

A scientist finds the distances d that two snakes travel in a time of t seconds. the equation 16t = d represents the relationship for the black mamba. the equation 1.5t = d represents the relationship for he rought-scaled snake. graph each equation. which is steeper? what does that tell you about how fast the two snakes are?

Answer 1

From the equation given, the time for the black mamba snake to cover distance d, will be d/16 while that for the the rought-scaled snake would be d/1.5.
Assume that the distance covered by both snakes is 200 meters;
Then, 
Time taken by the black mamba is 200/16  = 12.5 seconds, and
Time taken by the rought-scaled snake is 200/1.5 = 133.33 seconds
Clearly the black mamba is faster at 12.5 seconds compared with the rought-scaled snake.
