Nancy’s heart beats were faster. As you can see from the graph, Nancy is currently going at a rate of 1.25 beats per second as opposed to Lee’s 1.2 beats per second. You can figure this out from dividing Y/x=rate I can choose any point of the graph which I can divide. For this case I choose (20,25) So I divide 25/20 and I will get 1 5/20 rounding to 1 1/4 and then converted to 1.25 beats per second. Hope that helps!!
(you and 3 friends so we have 4 person <span>The group plans to ride each water ride twice.</span> so for each person we will pay 2(4.5+4+3.5)=2*12=24$ and for 4 person 24*4=96$ 100-96=4$ Answer: 4$)
but looking on gaven answers i understood that each person pay only for himself! so you paid 24$ and will get back 100-24=76$ Answer: 76$
