Question

4. A man travelled by car 12 km in 45 min. find his speed in m/sec.Answer step by step

Answer 1

Step-by-step explanation:

___________________________________________

Distance = 12 km

= 12000 m

Time = 45 m

= (45 × 60) sec

= 2700 sec

___________________________________________

• Formula used:

${\underline{\boxed{\mathbb{speed \: = \frac{distance}{time} }}}}$

___________________________________________

using above formula

${speed \: = \frac{distance}{time} }$

$speed = \frac{12000m}{2700sec}$

$= \frac{120}{27}$

$= \frac{40}{9} m /sec$

$= 4.44m/sec$
