<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.
It took Marty 60 minute to finish the report mentally you add 42 plus 8 is 50 plus 10 (because 18 minus 8 is 18) then that equals 60
