Question

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.

Answer 1

Speed of the walking is given as

`v = 0.84 m/s`

time to walk

`t = 49 minutes`

first we will convert it into seconds

`t = 49 * 60 = 2940 s`

now the distance covered will be given as

`d = v*t`

`d = 0.84 * 2940`

`d = 2469.6 m`

as we know that

`1 km = 1000 m`

so the distance in km is given as

`d = 2.469 km`
