Question

An athlete completes a round of circular tract with diameter 150 m in 5 min. What is the average speed V of the athlete in m/s? Answer with two decimal places

Answer 1

Answer:

Explanation:

From the question we are told that

 The diameter is $d = 150 \ m$

  The time taken is  $t = 5 \ min = 300\ s$

   

Generally the circumference is mathematically represented as

     $C =  d  *  \pi$

     $C =  150 *  3.142$

     $C =  471.3 \  m$

The average speed is mathematically represented as

      $v  =  \frac{C}{ t}$

     $v  =  \frac{471.3}{300}$

    $v =  1.571 \  m/s$
