Speed = distance / time
30 = d / 2.5
30 * 2.5 = d
75 = d
40 = d / 1.875
40 * 1.875 = d
75 = d
50 = d / 1.5
50 * 1.5 = d
75 = d
60 = d / 1.25
60 * 1.25 = d
75 = d
24 = 75 / time
time = 75/24
time = 3.125 hours
Answer:
It is a polynomial of doom. mwahahahah, you cant stop me spider man
Step-by-step explanation:
2.25t+ 5= 13.5t+ 14
⇒ 5- 14= 13.5t- 2.25t
⇒ -9= 11.25t
⇒ -9/11.25= t
⇒ -0.8= t
Final answer: t= -0.8~
Answer:
x = r(t + s) (second option)
Step-by-step explanation:
First add s to both sides and get x/r = t + s.
Then mutiply both sides by r to separate x and this is the final equation:
x = r(t + s)
