Question

The water level of a tank every minute since it began filling is indicated by segments A,B,and C on the graph

Answer 1

SOLUTION

From the graph

The slope of line A is

$m=\frac{60-20}{2-0}=20$

The slope of line B is

$n=\frac{80-60}{6-2}=5$

The slope of line C is

$p=\frac{110-80}{9-6}=10$

The least segment is the segment with the least slope.

The required arrangement is

$B,C,A$
