Answer:
100 seconds
Step-by-step explanation:
I've seen this question before. I know you didn't mean to put 858585.
The real question is "Kong took 15% percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 85 seconds. How many seconds did Nolan take?"
Now let's work!
Kong took 15% fewer seconds than Nolan took.
So Kong took 100%−15%=85%
Whatever Nolan's total was, Kong had 85% of that.
We know Kong took 85 seconds. 85% of Nolan's total is 85 seconds.
=100 seconds. 85%=15 seconds
Which means that Nolan took 100 seconds.
Glad I was able to help!!
