Answer:
3/10 kilos per hr
Step-by-step explanation:
1/4÷5/6=1/4×6/5
=6/20=3/10
The range refers to the area where the data points fall from the lowest to highest. Here, the lowest point is 437 and the highest is 1465. So the range is from 437 to 1465

Since the product of the slope is -1, hence the lines are perpendicular
<h3>Parallel and Perpendicular lines</h3>
Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1
Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;
Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3
Similarly for the coordinate points (-1, -7) and (1, -1).
Slope = -1+7/1+1
Slope of line 2 = 6/2
Slope = 3
Take the product of the slopes
Slope = -1/3 * 3
slope = -1
Since the product of the slope is -1, hence the lines are perpendicular
