Answer:
60
Step-by-step explanation:
lets say the number is X so:
X-3/4X=15
then multiple both sides by 4 then you will get
4X-3X=60
SO:X=60
Let
x----------> the number of students
y---------> the time in minutes
we know that
<span>If the time varies inversely with the number of students
</span>so
y=k/x
for x=3
y=16 min
16=k/3---------> k=48
y=48/x
for x=2
y=48/2-------> y=24 minutes
the answer is
24 minutes
