Question

an athlete cover one round of circular track of 7 m radius 44 second how much distance will it cover in 1 minutes

Answer 1

Distance of one round = 2 π r
= 2 × 22/7 × 7 m
= 44 m

Speed of athlete = Distance / Time
= 44 m / 44 s
= 1 m/s

Distance covered in 1 min (60 s)
Distance = Speed × Time
= 1 m/s × 60 s
= 60 m

∴ Athelete travels 60 m in 1 minute.

Answer 2

Given:

Radius of the circle $=7m$

Time $=44$ $sec$

To find:

The distance covered by the athlete in $1$ $min$.

Solution:

We have been given that the athlete covers a circle of radius $R=7m$ in $T=44s$, the athlete, runs on the periphery of the circle also known as the circumference of the circle .

We know,

The circumference of the circle is given by $C=2\pi R$

Substituting the values, we get

$C=2(\frac{22}{7} )(7)$

$C=44m$

Hence, the circumference of the circle is 44 m or the athlete covers a distance of 44 m in 44 seconds.

Therefore, the speed of the athlete is 1 m/s.

We know,

Speed of an object is the distance traveled by the object in a given time.

$s=\frac{d}{t}$

Hence,

$d=s$ × $t$

We have, $s=1m/s$     $;$ $t=1min=60s$

Hence, distance traveled by the object in $60s$ will be

$d=1$ × $60$

$d=60$ $m$

Final answer:

Hence, the athlete travels 60 meters in 1 minute.
