Question

calculate aspeed of the bus is 30km/h then w't is the speed of the is m/sec


​

Answer 1

$\Large{\textsf{\pink{\underline{ANSWER}}}}$

★ Speed of Bus = 30 km/h

On Conversion -

30 km/h = 30×5/18 = 8.3 m/s

Answer 2

$\red{ \underline{question} }: -$

calculate aspeed of the

bus is 30km/h then

what is the speed of the

in m/sec ?

$\mathfrak \red {\underline{solution }}: - \\ \\ we \: know \: \\ \\ \red{1 \: km \: = \: 1000 \: m \: } \: \: \: \: \: and \\ \\ \red{1 \: hour \: = 3600 \: sec} \\ \\ \purple{so} \:$

• 30 km/h

• 30 km = 30000 m

• 30 hour = 108000 sec

$now \\ \\ \purple {= > 30 \: km/h \: = \frac{30000}{108000} \: m/sec} \\ \\ \purple { = \frac{30}{108} \: m/sec} \\ \\ \purple{ = \frac{10}{36} \: m/sec} \\ \\ \fbox \red{divide \: numerator \: and \: denominator \: by \:10 } \\ \\ \huge{\purple{ = \frac{ \frac{10}{10} }{ \frac{36}{10} } \: m/sec}} \\ \\ \purple{ = \frac{1}{3.6} \: m/sec } \\ \\ \red{ = {3.6}^{ - 1} \: m/sec} \\ \\ \fbox{ \red{hence \: 30 \: km/h \: = {3.6}^{ - 1} \: m/sec.}} \\ \\ \\ \\ \fcolorbox{red}{aqua}{i \: hope \: i \: helps \: you.}$
