Question

A man covers 36 km in 1 hour. Find his speed in metres/sec.​

Answer 1

Distance covered = 36 km

Time taken = 1 hour

By converting the distance into m, we get

36 km = 36 × 1000 = 36,000 m

By converting the time into seconds, we get

1 hour = 60 × 60 = 3,600 seconds

We know that Speed = Distance / Time

Now, by converting the Speed into m/s, we get

Speed = 36,000/3,600 = 10 m/s.

Answer:

The speed in metres/sec is 10 m/s. (approx.)

Answer 2

$\color{skyblue}{\bigstar \large\underline{\boxed{\bf\pink{Question:-}}}}$

$\tt \red{A \: man \: covers \: 36 \: km \: in \: 1 \: hour.} \\ \tt \red{Find \: his \: speed \: in \: metres/sec.}$

$\color{skyblue}{\bigstar \large\underline{\boxed{\bf\pink{Answer:-}}}}$

$\red \dag \orange{ \boxed{ \sf{ Speed = \frac{Distance}{Time} }}}$

Here , distance = 36km = (36×1000)

= 36000 m

Time = 1 hour (1×60×60) = 3600 sec

$\red \dag \purple{ \boxed{ \sf{{Speed = \frac{ \cancel{36000}}{ \cancel{3600}}}}} }$

$\sf \blue{ \mapsto \: 10 \: m/sec }$
