Question

A computer performs a calculation in 2.5*10-5 seconds to solve a math problem. How long does the computer need to calculate the solutions to 3*106 math problems? (standard form)

Answer 1

Given :

A computer performs a calculation in
`2.5* 10^(-5)` seconds to solve a maths problem.

To Find :

How long does the computer need to calculate the solutions to
`3* 10^6` maths problems.

Solution :

Time taken to perform 1 calculation is
`2.5* 10^(-5)`.

`t=2.5* 10^(-5)\ s`

So, time taken to perform
`3* 10^6` calculations.

`T = t*( 3* 10^6)\\\\T = 2.5* 10^(-5)* 3* 10^6\\\\T = 75\ seconds`

Hence, this is the required solution.
