$\huge \tt \underline \orange {Correct \: Question}$

An athlete completes one round of a circular track of diameter 200m in 40 second. What will be the distance covered and the displacement at the end of 2 minutes 20 seconds.

$\huge \tt \underline \orange {Answer}$

$\bf\pink{d \: = \: 200 \: m} \\ \\ \bf \pink{ \implies r \: = \: 100 \: m } \\ \\ \bf\red{t \: = \: 2min \: 20sec \: = 140s}$

$\tt \purple {Number \: of \: Rounds \: Completed = \frac{140}{40} = 3.5 }$ $\\ \\ \huge \rm \fbox{ \pink {AB = \frac{2\pi r}{2} }}$

$\bf \green {(a) \: Distance \: Travelled \longrightarrow (2\pi r)( 3.5)}$

$\bf \green { \implies (2 \times \frac{22}{7} \times 100 \times 3.5)}$

$\bf \green { \implies (2 \times \frac{22}{7} \times 100 \times 3.5) = 2200 \: m}$ $\\ \\ \bf\red{(b) \: Displacement\longrightarrow 200 \: metre}$

Answer 2

correct question is- An athlete complete one round of a circular track of diameter 200m in 40 seconds. what will we distance covered and the displacement at the end of 2 minutes 20 seconds.
