Answer: 20.2 mph
Step-by-step explanation:
Given
Train travels 10.1 miles in half an hour i.e.
Distance [tex]d=10.1\ \text{miles}[/tex]
time [tex]t=0.5\ hr[/tex]
we know, [tex]\text{distance=speed}\times\text{time}[/tex]
Insert the values
[tex]\Rightarrow 10.1=v\times 0.5\\\Rightarrow v=20.2\ mph[/tex]
