Question

Find the distance travelled by a body in 5 minutes if it travels with a uniform speed of 20ms

Answer 1

Answer:

5minutes = 5*60 =300sec

Distance = speed * time

distance =20*300=6000m

i.e,6km

Answer 2

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

$\green{\tt{\therefore{Distance\:travelled=6\:km}}}$

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

$\green{\underline \bold{Given:}} \\ \tt: \implies Initial \: speed(u) = 20 \: m/s \\ \\ \tt: \implies Time \: taken = 5 \: min \\ \\ \red{\underline \bold{To \: Find:}} \\ \tt: \implies Distance \: travelled = ?$

• According to given question :

$\tt \circ \: Time = 5 \times 60 = 300 \: sec \\ \\ \tt \circ \: Acceleration =0 \: m {s}^{2} \\ \\ \tt \circ \: Initial \: velocity = 20 \: ms \\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies s=ut + \frac{1}{2}a {t}^{2} \\ \\ \tt: \implies s = 20 \times 300 + \frac{1}{2} \times 0 \times {300}^{2} \\ \\ \tt: \implies s =6000 + 0 \\ \\ \green{\tt: \implies s = 6 \: km} \\ \\ \green{\tt\therefore distance \: travelled \: by \: body \: is \: 6 \: km} \\ \\ \blue{\bold{Some \: related \: formula}} \\ \orange{\tt \circ \: v = u + at} \\ \\ \orange{\tt \circ \: {v}^{2} = {u}^{2} + 2as}$
