Coffee Detour Timeliness

Lisa wants to know if she can detour to get coffee on her way to work and still be on time. You are given four integers: the distance to work (D, in kilometers), the average speed of the car (S, in km/h), the extra distance due to the detour (E, in kilometers), and the available time (T, in minutes). Using the formula

\( \frac{D + E}{S} \times 60 \leq T \)

determine whether Lisa can afford the detour and still arrive on time.

inputFormat

The input consists of a single line containing four space-separated integers: D, S, E, and T. Here, D is the distance to work in kilometers; S is the average speed of the car in km/h; E is the extra distance due to the detour; and T is the total available time in minutes.

outputFormat

Output a single line with either "Yes" if Lisa can take the detour and still be on time, or "No" otherwise.
