Hello!
[tex]\large\boxed{\frac{5}{3}\text{ hours} \text{ or }100 \text{ min}}[/tex]
Use the equation d = s · t where:
s = speed
t = time
d = distance
Plug in the given distance and speed:
20 = 12 ·t
Divide both side by 12 to isolate for t:
20/12 = t
Simplify:
5 / 3 = t
Therefore, it took 5/3 hours to bike. We can convert this to minutes if necessary:
5/3 · 60 min (in one hour) = (60 · 5) / 3 = 100 min.
