Well, we gotta use this formula, \(\rm \color{blueviolet}{time = \dfrac{distance}{rate}}\) correct? So we know our distance is 315 kilo and our rate is , so plug in the values \(\rm \color{blueviolet}{time~=\dfrac{315kilo}{35kilo~per~hour}}\), so what is 315/35

OpenStudy (anonymous):

9

OpenStudy (anonymous):

Correct, so that makes our time 9h

OpenStudy (anonymous):

heres the next question http://prntscr.com/5pgkqb

OK so we are trying to find the time, correct?

OpenStudy (anonymous):

Remember the formula I gave above? We have to plug in the values, so for the first part he walked we have \(\rm \color{blueviolet}{time~=\dfrac{300ft}{4ft ~per ~sec}}\), so what is 300/4?

OpenStudy (anonymous):

75

OpenStudy (anonymous):

Good, so now for the second part we have \(\rm \color{blueviolet}{time~=\dfrac{250ft}{5ft~per~sec}}\)

OpenStudy (anonymous):

so 250/5 right is 50 right?

OpenStudy (anonymous):

Correct, so our times are 75 sec and 50 sec. Add them together

OpenStudy (anonymous):

145

OpenStudy (anonymous):

Ah, try again :P
