Answer:

2.5 km/h

Step-by-step explanation:

Here we have a distance problem where we are given the distance the time time:

Rate = ?

Time = 2hrs

Distance = 5km

The simplest way to do this is to rearrange the formula to suit our need and plug in the numbers:

[tex]R*T=D\\R*\frac{T}{T}=\frac{D}{T} \\R=\frac{D}{T}[/tex]

Now, plug in the numbers and solve:

[tex]R=\frac{D}{T}\\R=\frac{5}{2} \\R=2.5[/tex]
