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

Answer:

$d'=117\dfrac{3}{5}\ m$

Step-by-step 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

$d=\dfrac{3528}{1800}=1.96\ m$

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

$d'=\dfrac{588}{5}=117\dfrac{3}{5}\ m$

Hence, this is the required solution.

Answer 2

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