Problem of the Week

Oct 31, 2021

 

 

 

 

 

 

Did you figure it out?

 

Solution:  The distance between the pig and the sheep closes at a rate of 11 – 3 = 8 miles per hour. The distance between the border collie and the sheep closes by 25 – 20 = 5 miles per hour. Since the distance between the pig and the sheep closes faster than the distance between the border collie and the sheep, the pig catches up faster. 

 
 
 
 
 

 

 

 

 

 

 

Did you figure it out?

Solution:  Since the farmer sleeps through his alarm 3 times every 12 days, he wakes up to his alarm clock 9 times every 12 days. So, the alarm clock is successful 9 ÷ 12 = ¾ of the mornings it’s used. The duck wakes up the farmer 2 ÷ 3 = of the mornings it quacks. Since ¾ is more than , the alarm clock is more effective than the duck.
