Relax. If you simply know what microsecond means, the whole problem will be easy.
Ok. Microsecond is . This means there are 1,000,000 (wow. that's alot) microseconds in a second. Now, how many seconds are there is a minute? 60. So multiply 1,000,000 by 60, which equals 60,000,000 (by the way, 60,000,000 microseconds is 1 minute, if you didn't know) Now, the question asks you how many instructions can it execute in FOUR (4) minutes. So multiply THAT by 4, which is 240,000,000. So 4 minutes is 240,000,000. However, we're not talking about 1 instruction per microsecond here. We're talking about THIRTY-SIX (36)! So we have to multiply 240,000,000 by 36, which finally equals 8,640,000,000.
So, computer executes 8,640,000,000 instructions in 4 minutes.
Alright. Good luck.

A microsecond is a millionth of a second. So in a millionth of a second this computer
executes 36 instructions. So in a million microseconds (which is 1 second) the computer
does 36 million instructions.
.
So what have we got at this point? We have found that each second the computer can execute
36 million instructions. So in 60 seconds (which is 1 minute) the computer can execute
36 million instructions times 60 ... and this is (36*60) million instructions. Multiplying
this out you get 2160 million instructions each minute. But you are asked to find the number
of instructions in 4 minutes ... so you multiply 2160 million times 4 to find out that in
4 minutes the computer does (2160*4) million or 8640 million instructions.
.
In long form this is 8,640,000,000 instructions in 4 minutes.
.
Hope this clarifies it for you ...
