Heather and Matthew walk eastward with a speed of .84 m/s east. If it takes them 49 minutes to walk to the store, how far have they walked. Answer in units of km.

Respuesta :

Speed of the walking is given as

[tex]v = 0.84 m/s[/tex]

time to walk

[tex]t = 49 minutes[/tex]

first we will convert it into seconds

[tex]t = 49 * 60 = 2940 s[/tex]

now the distance covered will be given as

[tex]d = v*t[/tex]

[tex]d = 0.84 * 2940[/tex]

[tex]d = 2469.6 m[/tex]

as we know that

[tex]1 km = 1000 m[/tex]

so the distance in km is given as

[tex]d = 2.469 km[/tex]
