Step-by-step explanation:
She carried her wood doll in her bare arms, singing under her breath all she could make up about him. And when in a bright morning she peeped in on the chest, so sweet-scented and secret it seemed that she took her doll with her into it--just as Henry himself had done.
Answer:
Given:
the speed of a car is 5 m/s.
\begin{gathered} \\ \\ \end{gathered}
To Find:
then the distance covered in 2 hours and 30 mins
\begin{gathered} \\ \\ \end{gathered}
Solution:
◐ Now, here we have got the speed of the car in m/s let's convert it into km/phr as we have to find the distance per km.
\begin{gathered} \\ \\ \end{gathered}
\begin{gathered}{ : \implies} \sf1m \: per \: sec = \cancel\dfrac{3600}{1000} \: km \: per \: hr \: \: \: \: \\ \\ \\ { : \implies} \sf \: 1m \: per \: sec = 3.6km \: per \: hr \: \: \: \: \: \: \: \: \: \\ \\ \\ { : \implies} \sf \: 5m \: per \: sec = 3.6 \times 5 \: km \: per \: hr \: \\ \\ \\ { : \implies} \sf \: 5m \: per \: sec = 18km \: per \: hr \: \: \: \: \: \: \: \: \: \: \: \: \end{gathered}:⟹1mpersec=10003600kmperhr:⟹1mpersec=3.6kmperhr:⟹5mpersec=3.6×5kmperhr:⟹5mpersec=18kmperhr
\begin{gathered} \\ \\ \end{gathered}
\therefore{ \underline{ \pink{ \text{5m \: per \: second = 18km \: per \: hour}}}}∴5m per second = 18km per hour
\begin{gathered} \\ \\ \end{gathered}
★Now the speed of the car is 18 km / phr ★
➺ So, we have to find the distance
{\mathfrak{\underline{\pink{As \: we \:know \:that}}}}Asweknowthat
\begin{gathered} \\ \\ \end{gathered}
\longrightarrow \: \sf distance = speed \times time⟶distance=speed×time
\begin{gathered} \\ \\ \end{gathered}
❍ Let's substitute the values now ,
\begin{gathered} \\ \\ \end{gathered}
\begin{gathered}{ : \implies} \sf \: distance = 18 km \: per \: hr \: \times 2 \frac{1}{2} \:hr \: \\ \\ \\ { : \implies} \sf \: distance = 45km \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \end{gathered}:⟹distance=18kmperhr×221hr:⟹distance=45km
\begin{gathered} \\ \\ \end{gathered}
{\therefore {\rm{\orange{ \: the \: distance \: travelled \: by \: the \: car \: = 45km \bigstar}}}}∴thedistancetravelledbythecar=45km★
\begin{gathered} \\ \\ \end{gathered}
\large\rm{More \:to \:know:}Moretoknow:
Speed = distance / time
Time = distance / speed
SI unit of speed = m/s
SI unit of time = second
SI unit of distance = meter
hope this helps
