Question

!!!!!!!!!!!STThe length of a jogging trail is 3528 m. A jogger wants to complete the trail within 30 min. How many meters must the jogger travel each minute?

A. 117 4/15 m

B. 117 3/10 m

C. 117 1/3 m

D. 117 3/5 m

Answer 1

divide 3528 by 30
3528 / 30 = 117.6 = 117 6/10 = 117 3/5 m = D

Answer 2

`d'=117(3)/(5)\ m`

Explanation:

It is given that,

The length of a jogging trail is 3528 m, d = 3528 m

A jogger wants to complete the trail within 30 min, t = 1800 s

We know that, 1 minute = 60 seconds

We need to find the distance the jogger must travel each minute. The distance covered in 1 second is

`d=(3528)/(1800)=1.96\ m`

So, the distance covered in 60 seconds is,
`d'=1.96* 60=117.6\ m`

`d'=(588)/(5)=117(3)/(5)\ m`

Hence, this is the required solution.
