<h2>Answer:</h2>

The time Marty spend on his book report is:

60 minutes or 1 hour

<h2>Step-by-step explanation:</h2>

It took Marty 42 minutes to write a book report then he spend 18 minutes correcting his report.

This means that the total time i.e. the overall time he spends on his book is:

Time he spend on writing the book+ The time he spend on correcting his book report

Hence,

Total time= 42 minutes+18 minutes

i.e.

Total Time= 60 minutes

Also, we know that:

1 hour= 60 minutes.

Hence, his total time is: 60 minutes or 1 hour.
