heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
Thank you for posting your question here at brainly. Below is the solution for the above problem. I hope the answer will help you.
<span>a² + b² = c²
3² + 4² = c²
25 = c²
c = 5</span>
Y=x2
Y=the answer
X= Mai skated
X2= Mai’s distance times 2 equals Clare’s distance
Answer:
8 more minutes.
I think the perfect version in your question is:
<em>McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when McGill finish typing his paper</em>
Given that:
- 270 words in six minutes <=> 1 minute =
= 45 words
So, the total minutes he needs to finish the paper if he keeps waving at the same rate is:
=
= 14 minutes.
So he needs 14 minutes to finish writing the paper, but he wrote 270 words in 6 minutes already, so it will take him 14-6 = 8 more minutes.
Hope it will find you well!
