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

Step-by-step 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  =  (C)/( t)`

`v  =  (471.3)/(300)`

`v =  1.571 \  m/s`
