$</p><p>\mathfrak {\bold{\red {\boxed{\underline{❥Given:-}}}}}</p><p>$

$\mathfrak{\bold{\underline{Distance \: covered=120km}}}</p><p>$

$\mathfrak{\bold{\underline{Time \: taken=4hrs}}}</p><p></p><p>$

$\mathfrak{\bold{\underline{Speed=Distance/Time}}}</p><p>$

$\mathfrak{\bold{\underline{S=120/4}}}$

$\mathfrak{\bold{\underline{S=40km/hr}}}$

$\mathfrak{\small {\bold{\red{\underline{Car \: decreases \: its \: speed \: while \: returning=6km/hr}}}}}</p><p>$

$\mathfrak{\bold{\underline{=>40-6}}}</p><p>$

$\mathfrak{\bold{\underline{=>34km/hr}}}</p><p>$

$\mathfrak{\small{\bold{\red {\underline{Time \: taken=Distance/speed}}}}}</p><p>$

$\mathfrak{\bold{\underline{T=120/34}}}$

$\mathfrak{\bold{\underline{=>3hrs52mins}}}$
