Question

Yesterday Priti typed an essay of 5000 words at the speed of 60 words per minute. Today she typed the same essay faster and her speed was 15%

Answer 1

Answer:

Time reduced by 10.87 Mins

Step-by-step explanation:

Word typed =  5000

Speed = 60 words per minute

Time taken = Word typed/ Speed

Time Taken = 5000/60

Time taken = 250/3 Minutes

Time taken = 83.33 Mins

Speed increased by 15 %

Increased speed = 60 + 60(15/100) = 69 word/min

Time taken = 5000/69

Time Taken = 72.46 Mins

Time reduced by 83.33 - 72.46 = 10.87 Mins
