Question

the speed of a car is 5 m/s, then the distance covered in 2 hours and 30 min is ___​

Answer 1

◇ Required answer :-

Since speed=distance/time. In given situation we have speed=5 m/s and time 1 hour but since speed is in seconds so we have to convert 1 hour into secconds.

I hour=60 min×60 secs each i.e 3600 seconds in 1 hour

Now speed=distance/time

Distance=speed×time

I.e x=5×3600=18000 meters

I.e in 1 hour it will cover 18 km.

Hope it helps

Have a awesome day

Answer 2

Given:

• the speed of a car is 5 m/s.

To Find:

• then the distance covered in 2 hours and 30 mins

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.

${ : \implies} \sf1m \: per \: sec = \cancel\dfrac{3600}{1000} \: km \: per \: hr \: \: \: \: \\ \\ \\ { : \implies} \sf \: 1m \: per \: sec = 3.6km \: per \: hr \: \: \: \: \: \: \: \: \: \\ \\ \\ { : \implies} \sf \: 5m \: per \: sec = 3.6 \times 5 \: km \: per \: hr \: \\ \\ \\ { : \implies} \sf \: 5m \: per \: sec = 18km \: per \: hr \: \: \: \: \: \: \: \: \: \: \: \:$

$\therefore{ \underline{ \pink{ \text{5m \: per \: second = 18km \: per \: hour}}}}$

★Now the speed of the car is 18 km / phr ★

➺ So, we have to find the distance

${\mathfrak{\underline{\pink{As \: we \:know \:that}}}}$

$\longrightarrow \: \sf distance = speed \times time$

❍ Let's substitute the values now ,

${ : \implies} \sf \: distance = 18 km \: per \: hr \: \times 2 \frac{1}{2} \:hr \: \\ \\ \\ { : \implies} \sf \: distance = 45km \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

${\therefore {\rm{\orange{ \: the \: distance \: travelled \: by \: the \: car \: = 45km \bigstar}}}}$

$\large\rm{More \:to \:know:}$

• 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
