Question

Brendon finished an obstacle course in 22.5 minutes. Tobias finished the course 85 seconds after Brendon. How long did it take Tobias to finish?

Answer 1

23.35 minutes

Explanation:

Brendan finished in 22.5 minutes. Tobias finished 85 seconds after. Just add 85 seconds to 22.5 minutes. There are 100 second in 1 minute. Since Brendan is already at 22.5, there is only 0.5 left to get to 23. 0.5 in this case means 50 seconds. You do 85 - 50 = 35. Now, you are at 23 minutes. Add 35 seconds to that to get to 23.25 minutes.
