Question
A computer can perform 1,000,000 calculations per second. At this rate, how many HOURS will it take this computer to perform the\(3.6 x 10^11\) calculations required to solve a problem?
a 60 b 100 c 600 d 1000 e 6000 b. 100 per hour the computer performs \(3600 X 10^6\) calculations which is = \(3.6 X 10^9\) So time taken to perform \(3.6 X 10^11\) calculations = \(3.6 X 10^11\)/\(3.6 X 10^9\) = 100hrs

A. 60 B. 100C. 600 D. 1,000 E. 6,000 Always read carefully. It could be easy to read quickly and miss that the rate is given in seconds but the answer choices are given in hours. The first step is to convert the rate into hours. This will make the calculations easier. 1000000 calculations = 1 x 10^6 calculations The rate is 3.6 x 10^9 calculations per hour. 3.6 * 10^9 calculations per hour= 3.6 * 10^11 calculations per x hours (3.6 *10^9 calculations per hour) ÷ (3.6 * 10^11 calculations) = x hours x hours = 10^2 = 100

B) 100
1000000 is 10^6, therefore we have the speed of 10^6 per second or 3600x10^6 = 3.6x10^9 per hour. Now, we need to make 10^2 or 100 times more calculations, therefore it will take 100 hours.

B. (3.6 x 10^11)/10^6 = 36 x 10^4 seconds = 100 hours

B) 100
(3.6 x 10^11)/(60x60x10^6)
= 10^4/100 = 100 hours

36*10^10/10^6 = 36*10^4/(36*10^2) = 100 hours

(B)
total time in secs = 3.6 * 10^11/10^6 = 3.6 * 10^5 secs
= 3.6 * 10^5/3600 hrs = 100 hrs

a)60 b) 100 c) 600 d) 1,000 e) 6000 B 1 x 10^6 calc/sec = 1 x 10^6 calc/sec * 60 sec/min * 60 min/hr = 1 x 10^6 calc/sec * 3600 sec/hr = 1 x 10^6 calc/sec * 3.6 x 10^3 sec/hr = 3.6 x 10^9 calc/hr 3.6 x 10^11 calc / 3.6 x 10^9 calc/hr = 10^2 hr = 100 hr

I would say answer B Because the computer can calculate 1,000,000 calculations per second OR 3600,000,000 (3600*1,000,000) per hour, which is similar to 3.6*10^9. The question states a problem of the magnitude 3.6^11
119 = 2, therefore 10^2 = 100

100.
Here's the calculation you should have derived:
(3.6 x 10^11 calc) x (1sec/10^6) x (1min/60sec) x (1hr/60min)

A. 60 B. 100 C. 600 D. 1,000 E. 6,000 Computer can perform = 10^6 calculations /sec So for 3.6 x 10^11 calculations it will require 360000 seconds for computing. i.e., 360000 seconds = 360000/ (60 x 60) hours = 100 hours.
