A train takes one hour longer to travel d miles at its normal speed than it would if it were traveling 10 miles faster. Which of following equations could represent the equation to find the train's normal speed \(s\), in miles per hour?
(A)\(\frac { d } { s + 10 } = s + 1\) (B)\(\frac { d } { s } = \frac { d } { s + 1 } \) (C)\(\frac { s } { s + 10 } = d\) (D)\(\frac { d } { s + 10 } - \frac { d } { s } = 1\) (E)\(\frac { d } { s } - \frac { d } { s + 10 } = 1\)
E
