It's 60 minutes because 450÷10 is 45 so he has to bike for 45 minutes and a 15 minute break would make it 60 minutes
Given that a side length is that means its parallel side is also 16. So 16 + 16 is 32 and 72 - 32 is 40 and 40 divided by 2, for two sides of the rectangle youll get 20. With the length being 20 and width being 16, 20 times 16 will get you 320m^2 which is the area.
So k=1000 like 4k=4 000 so 6/7 of a thousnad =0.857142857 so times 6=0.857142857
Answer:
<h2>D. 5 hours</h2>
Step-by-step explanation:
rt=d
rt+rt=900
80t+100t=900
180t=900
18t=90
2t=10
t=5
5 hours
80*5+100*5=900
$840 - 20% = $672 so $672/6 = $112, therefore the answer is $112.
