Answer 2

$\mathfrak{\underline{\underline{ANSWER:}}}$

${\bold{\therefore Distance\:between\:two\:towns=422.5\:km}}$

$\bold{\underline{\underline{Step-by-step\:explantion:}}}$

• In the given question information given about two cars start from town P and town Q in opposite direction at the speed of 70 km/h and 60 km/h. After 11/4 hours the distance between those two cars is 65 km apart.

• We have to find the distance between two towns.

$\underline \bold{Given : } \\ \implies Speed \: of \: car \: P = 70 \: kmh \\ \\ \implies Speed \: of \: car \: W = 60\: kmh \\ \\ \underline \bold{To \: Find: } \\ \implies Distance \: between \: town \: P \: and \: Q = ?$

• According to given question :

$\bold{For \: car \: P : } \\ \implies Distance = speed \times time \\ \\ \implies D = \cancel{70} \times \frac{11}{ \cancel4} \\ \\ \implies D = \frac{ \cancel{385}}{ \cancel2} \\ \\ \bold{\implies D = 192.5 \:km} \\ \\ \bold{For \: car \: Q : } \\ \implies Distance = speed \times time \\ \\ \implies D_{2} = \cancel{60} \times \frac{11}{ \cancel4} \\ \\ \implies D_{2} = 15 \times 11 \\ \\ \bold{\implies D_{2} = 165 \: km} \\ \\ \bold{ Total \: distance \: between \: town \: P \: and \: Q :} \\ \implies Distance \: covered \: by \:car \: P+ car \: Q+ 65 \: km \\ \\ \implies Total \: Distance = d + d_{2} + 65 \\ \\ \implies Tota l \: Distance = 192.5 + 165 + 65 \\ \\ \bold{\implies Tota l \: Distance =422.5 \:km} \\ \\ \bold{\therefore Distance \:between \: town \: p \: and \: q }\\ \bold{ \: \: \: \: is \: 422.5 \: km}$
