• Distance by road from their house to the school is 100 m.
• Time Given 50 sec

`\rule{70mm}{2.2pt}`

`\large \purple{ \rm{To \: find↦}}`

• Carlos speed

`\rule{70mm}{2.2pt}`

`\large \purple { \rm{Assumption↦}}`

• let the speed be x

`\rule{70mm}{2.2pt}`

`\large \purple { \rm{ To \: find \: speed \: we \: use↦}}`

`{\boxed{ \rm{Speed= \frac{ Distance } {Time}}}}`

`\rule{70mm}{2.2pt}`

`\large \purple{ \rm{Substitute \: value \: according \: to \: formula. \: }}`

`\large \rm{s = (100)/(50) }~~~~~~~~~~~~~~~~~~~~ \\ \\ \large \rm{s = \cancel (100)/(50) }~~~~~~~~~~~~~~~~~~~~ \\ \\ \large \rm{s = 2 m/s \: or \: 7.2km/h }`
