Question

Calculate the distance in km that Allex can run in 2 hours if she maintains the constant average speed of 8 km/h.

Answer 1

\[d = rt\]

Answer 2

You can figure this out by looking at the units, as well. You're looking for a distance, and you have numbers which have units of time, and length/time. How can you combine them to end up with just length?

Answer 3

16

Answer 4

Just plug in what was given, the equation d=rt , distance = rate(8km/hr) x time(2 hours),
which gives you 16 km.
