Answer 1

$\large\bold{Question:\\}$

If a bike covers 108 Km in two hours. Find its speed in m/sec.​

$\large\bold{Given:}$

Distance: 108 Km,

Time: 2 Hours,

$\large\bold{To\:FinD:}$

Speed in m/sec.

$\large\bold{Formula\:used \:for \:solving:}$

• $\large\mathfrak{Speed=\frac{Distance}{Time} }$

• To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18, So $\frac{5}{18}$

   $\huge\fcolorbox{black}{lime}{AnsweR:}$

• $\large\mathfrak{\frac{108}{2}=54\:km/hr }$

• $\large\boxed{\mathfrak{54*\frac{5}{18} }}$         =   $\large\boxed{\mathfrak{\frac{270}{18} }}$    = $\large\mathfrak{15\:m/sec.}$

Answer 2

$\huge \colorbox{lightgreen}{answer}$

Distance = 108 km

time = 2 hours

$\bf \: speed \: = \frac{distance}{time} \\ \\ \bf \: = \cancel \frac{108}{2} km / hr \\ \\ \bf \: = 54km /hr \\ \\ \bf \: now \: speed \: in \: m/s = \frac{54 \times 1000}{3600} m/s \\ \\ \bf \: = 15m/s$

hope it helps you dear...
