Question

Joanna has a big paper due. yesterday, she started typing her hand-written draft. she typed 862 words of it and saved her work to continue later. if she types at a rate of 70 words per minute, and the paper is 1,562 words long, how much more time does she have to spend typing? a. 10 minutes b. 15 minutes c. 18 minutes

Answer 1

10 minutes

Explanation:

if 70 words = 1minute

862 words will be 862÷70=12.31 minutes

1,562 words will be 1562÷70=22.31 minutes

time needed to finish will be 22.31-12.31= 10 minutes

So the total time needed to finish will be 10 minutes
