Printer a prints 36 pages every 1.5 minutes. printer b prints 114 pages every 3 minutes printer c prints 115 pages every 5 minutes which printer prints the fastest?

Printer B prints faster

Solution:

Given that Printer A prints 36 pages every 1.5 minutes

Let "x" be the number of pages printed in 1 minute

Therefore,

1.5 minutes = 36 pages

1 minute = x pages

By cross-multiplication,

Thus unit rate of Printer A is: In 1 minute, Printer A can print 24 pages

Printer B prints 114 pages every 3 minutes

Similarly,

3 minutes = 114 pages

1 minute = x pages

This forms a proportion. Therefore by crossmultiplying we get,

Thus unit rate of Printer B is: In 1 minute, Printer B can print 38 pages

Printer C prints 115 pages every 5 minutes

Similarly,

5 minutes = 115 pages

1 minute = x pages

This forms a proportion. Therefore by crossmultiplying we get,

Thus unit rate of Printer C is: In 1 minute, Printer C can print 23 pages

unit rate of printer B > unit rate of printer A > unit rate of printer C

On comparing the unit rate of Printer A, B, C we see that, printer B prints faster

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

no solution exists the way you wrote the equation.
