Question

A car travels a distance of 360 km in 5 hours. what is the speed in m/s?

Answer 1

Answer:

distance travelled = 360 km

time taken = 5 hours(300 minutes)

speed = distance travelled

---------------------------

time taken

= 360

------

300

= 1.2 metre per second

ANSWER = 1.2 m/s

Answer 2

Answer:

$\large\underline{\underline{\red{⚝{\pmb{\sf{\:Given :-}}}}}}$

➥ Distance covered = 360 km

➥ Time = 3 hours

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{\red{⚝{\pmb{\sf{\:To \: Find :-}}}}}}$

➥ Average Speed = ?

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{\red{⚝{\pmb{\sf{\:Solution :-}}}}}}$

❒ We know that :

$\large\green\bigstar{\underline{\boxed{\color{maroon}{\sf{Ave. \: Speed = \dfrac{Total \: distance}{Total \: time} }}}}}$

❒ Average Speed :

$\large{:\longmapsto{\sf{Ave. \: Speed = \dfrac{360}{3}}}}$

$\large{:\longmapsto{\sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {\cancel\dfrac{360}{3}}}}$

$\large\blue{:{\longmapsto{\pink{\underline{\overline{\sf{ 120 km/h}}}}}}}$

❒ Hence :

❝ Average Speed of the car is 120 kmh .❞
