Question

A car is moving on a circular track of circumference 210m it complete one round in 30 second find the speed of the car

Answer 1

Solution :

⏭ Given:

✏ Circumference of circular path = 210m

✏ Time interval = 30s

⏭ To Find:

✏ Speed of the car

⏭ Concept:

✏ Speed is defined as ratio of distance covered to the time interval.

⏭ Formula:

✏ Formula of speed is given by

$\star \: \underline{ \boxed{ \bold{ \sf{ \pink{ \large{speed = \dfrac{distance}{time}}}}}}} \: \star$

⏭ Calculation:

$\implies \sf \: speed = \dfrac{210}{30} \\ \\ \implies \: \underline{ \boxed{ \bold{ \sf{ \orange{ \large{speed = 7 \: mps}}}}}} \: \star$

⏭ Additional information:

• Speed is scalar quantity.
• Distance is also scalar quantity.

Answer 2

$\mathtt{ \huge{ \fbox{Solution :)}}}$

Given ,

• Distance (d) = 210 m
• Time (t) = 30 sec

We know that ,

$\large \mathtt{ \fbox{Speed \: (s) = \frac{Distance \: (d)}{Time \: (t)} }}$

Thus ,

S = 210/30

S = 7 m/s

Hence , the speed is 7 m/s
