A computer performs a calculation in 2.5 x 10^-5 seconds to solve a math problem.

How long does the computer need to calculate the solutions to 3 x 10^6 math problems?

SOLUTION

The time taken to one question = 2.5 x 10^-5 seconds

For 3 x 10^6 math problems = 2.5 x 10^-5 X 3 x 10^6

= 7. 5 X 10^-5 X 10^6

= 7. 5 X 10 ^ -5 + 6

= 7. 5 X 10^1 seconds
