Answer:
Current time that is shown by watch is 10 : 00 AM & Watch is getting slow by 2 minutes for each hour in a day .
Exigency To Find : What will be the time after 12 hrs ?
⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀
⠀⠀⠀Given that ,
⠀⠀⠀⠀⠀⠀⠀⠀▪︎ ⠀The Current time that is shown by watch is 10 : 00 AM
⠀⠀⠀⠀⠀⠀⠀⠀▪︎ ⠀Watch is getting slow by 2 minutes for each hour .
⠀⠀⠀⠀⠀Now , As we have to find time that is shown by watch after 12 hrs ,
Therefore,
⠀⠀⠀⠀⠀⠀The time that get slower ( or late ) in 12 hrs will be ⠀
\begin{gathered}\qquad \qquad \sf Time \: get \:slower \:= \: 12 \times 2 \: min \:\:\\\end{gathered}
Timegetslower=12×2min
\begin{gathered}\qquad \qquad \bf Time \: get \:slower \:= \: 24 \: min \:\:\\\end{gathered}
Timegetslower=24min
\begin{gathered}\qquad :\implies \pmb{\underline{\purple{\:Time \: get \:slower_{(12 \:hrs\:)} \:= \: 24 \: min\: }} }\:\:\bigstar \\\end{gathered}
:⟹
Timegetslower
(12hrs)
=24min
Timegetslower
(12hrs)
=24min
