Bess jogs 1.5km in 10min, what is her average speed?

Question

it's a science: physics question

Answer 1

First we change all the variables into S.I. units:

1.5 km -> 1500m

10 min -> 600s

As speed is defined as (distance)/(time), we have

(speed) = 1500/600

(speed) = 2,5 m/s

Answer 2

.15km/min
