Setup

d : = $\func$rand(5, 20)

s : = $\func$rand(5, 10)

a : = $\func$rand(5, 10)

Conditions: $\left(\vphantom{ a<s}\right.$a < s$\left.\vphantom{ a<s}\right)$

Conditions: $\left(\vphantom{ \frac{60d}{s}=\left\lfloor \frac{60d}{s}\right\rfloor }\right.$${\frac{{60d}}{{s}}}$ = $\left\lfloor\vphantom{ \frac{60d}{s}}\right.$${\frac{{60d}}{{s}}}$$\left.\vphantom{ \frac{60d}{s}}\right\rfloor$$\left.\vphantom{ \frac{60d}{s}=\left\lfloor \frac{60d}{s}\right\rfloor }\right)$ [Total time is an integral number of minutes.]

Conditions: $\left(\vphantom{ \frac{60d}{a}=\left\lfloor \frac{60d}{a}\right\rfloor }\right.$${\frac{{60d}}{{a}}}$ = $\left\lfloor\vphantom{ \frac{60d}{a}}\right.$${\frac{{60d}}{{a}}}$$\left.\vphantom{ \frac{60d}{a}}\right\rfloor$$\left.\vphantom{ \frac{60d}{a}=\left\lfloor \frac{60d}{a}\right\rfloor }\right)$ [Total time is an integral number of minutes.]
