Question

If you walk at a constant speed of 4.5 m/s, how many km can you walk in half an hour? how do you solve this?

Answer 1

Its 8.1 km
So you multiply 4.5 times 60 to find the distance for a minute then you multiply this number by 30 to find the distance in meters for half an hour.
Finally you convert the meters by dividing it by 1000
