Week 315 (22nd September 2023)

Harriet is typing up her first assignment since joining a new college.  

Harriet types a constant number of words per minute.  

She takes 8 minutes to type 416 words.  

How long does it take her to type an assignment of 1534 words?  

Give your answer in minutes and seconds. 


First, we can find her typing speed in words per minute.  

To find typing speed: speed = words/time   

Speed = 416 words/8 mins = 52 words per minute 

If we substitute in what we know… 

52 = 1534/time  

…And rearrange to find time  

time = 1534/52 = 29.5mins, in minutes and seconds that is 29mins and 30 seconds.
