How many seconds did Nolan take?

Answer 1

Answer:

Nolan took 100 seconds.

Step-by-step explanation:

Given:

Kong took 15%, percent fewer seconds than Nolan took to complete his multiplication timed test.

Kong took 85 seconds.

Now, to find the number of seconds Nolan take to complete the test.

Let the number of seconds Nolan take be $x.$

Kong took = 85 seconds.

As, given Kong took 15%, percent fewer seconds than Nolan took.

Now, to get the number of seconds Nolan took:

$x-15\%\ of\ x=85$

$x-\frac{15}{100} \times x=85$

$x-0.15x=85$

$0.85x=85$

Dividing both sides by 0.85 we get:

$x=100.$

Therefore, Nolan took 100 seconds.
