Question

The speed of an autorikshaw is 42 km/hour.It travels continuously for 3 hours 50 minutes.what is the distance travelled by it?

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Distance\:travelled=161\:km}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt:\implies Speed \: of \: autorikshaw = 42 \: km \: h \\ \\ \tt:\implies time = 3 \: hour \: 50 \: min \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Distance \: travelled =?$

• According to given question :

$\tt \circ \: Speed = 42 \times \frac{5}{18} = \frac{210}{18} \: m/s \\ \\ \tt \circ \: Time = 230 \times 60 = 13800 \: sec \\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies Distance = Speed \times Time \\ \\ \tt: \implies Distance = \frac{210}{18} \times 13800 \\ \\ \tt: \implies Distance = \frac{2898000}{18} \\ \\ \tt: \implies Distance =161000 \: m \\ \\ \green{\tt: \implies Distance = 161 \: km} \\ \\ \bold{ \blue{Some \: related \: formula}} \\ \orange{\tt \circ \: v = u + at} \\ \\ \orange{\tt \circ \: {v}^{2} = {u}^{2} + 2as} \\ \\ \orange{\tt \circ \:s = ut+ \frac{1}{2} {at}^{2} }$

$\purple{\therefore{Distance\:travelled=161\:km}}$

$\orange{\bold{Step-by-step\:explanation:}}$

• Given :

》Speed = 42 km/hr

》Time = 3 hour 50 min

• To find :

》Distance travelled = ?

• According to given question :

$\bold{\pink{By \:formula \: of \: motion}} \\ \green{ \implies Distance = Speed \times Time} \\ \\ \blue{\implies Distance = 42 \times \frac{23}{6}} \\ \\ \red{\implies Distance = 7\times 23} \\ \\ \purple{\implies Distance =161 \: km}$
