Ok, so here, we have the unit rate of the snail. Now, we need to set up a proportion.
60/1 = 120/x
Now, cross multiply.
60*x = 120*1
60x= 120
Now divide to solve for x.
60x/60 = 120/60
x = 120/60
x= 2
Now our final answer is 2.
Final answer:- The snail will take 2 minutes to crawl 120 feet
First add the seconds you have 45 +5+10 seconds which equals 60 seconds or 1 minutes. Now add the minutes 9 + 7 + 12 minutes = 28 minutes then add that 1 minutes that you got from the seconds 28 + 1 minute = 29 minutes 7:40 + 20 minutes = 8:00 + 9 minutes = 8:09 am. So Marsha arrived to school at 8:09 am. Comment if you have any questions.
