Answer:

Chuck's rate of travel = 63mph

Step-by-step explanation:

Given chuck travels 252 miles and dana travels 228 miles. Given that they both take same time to travel .

Let the travelling time be T.

Also given that the speed of chuck is 6mph greater than that of dana's.

let the speed of chuck be x. Now

Speed = \frac{distance }{time}

x= \frac{252}{T}

Now for Dana's speed

x-6= \frac{228}{T}

When we divide both the equations we get

\frac{x}{x-6}=\frac{252}{228}

\frac{x}{x-6}=\frac{63}{57}

x=63mph

<h2>63 m/h</h2>

Step-by-step explanation:

       Chuck travels 252 miles and Dana travels 228 miles. Their rates of travel (speeds) differ by 6 mph. Chuck travels faster.

       Let us assume Dana's speed to be x\frac{m}{h}. Then Chuck's speed is (x+6)\frac{m}{h}.

       Now, their times of travel are the same.

Speed=\frac{Distance}{\textrm{Time Taken}}

\textrm{Time Taken = }\frac{Distance}{Speed}

\frac{252m}{x+6\frac{m}{h} }=\frac{228m}{x\frac{m}{h} }

\frac{x+6}{x}=\frac{252}{228}

\frac{6}{x}=\frac{252}{228}-1=0.10526

x=\frac{6}{0.10526}=57\frac{m}{h}

∴ Chuck's rate of travel = x+6=57+6=63\frac{m}{h}

spinner spun 2: there both 1/7 i think im

only in 7th grade ;-;

Step-by-step explanation: well there are 7 spaces so the probabilty

of it landing on an odd space on the wheel is how many odd numbers there are over 7 . and there is only 1 three so the chance that it will not land on 3 is 6/7.  there is a 2/7 chance it will land on 4 or 5. and im not to sure abt the last one but like i said im  only in the 7th grade i am taking p classes tho so the rest should be right. :D
