Michael has biked \( \frac{4}{5} \) of the total distance in 2 hours. To find the total time to complete the entire bike trail, we can set up a proportion.
Let \( T \) be the total time to travel the entire bike trail. Since he has completed \( \frac{4}{5} \) of the distance in 2 hours, we can express this as:
\[ \frac{4}{5}T = 2 \text{ hours} \]
To find \( T \), we can solve for it:
\[ T = 2 \text{ hours} \times \frac{5}{4} \]
Calculating this gives:
\[ T = \frac{10}{4} \text{ hours} = 2.5 \text{ hours} \]
Thus, the total time it will take him to complete the entire bike trail is 2 and 1 half hours.
The correct response is:
212 hours, 2 and 1 half hours.
