3*(1 h 25 min). bbhhhvff

Step-by-step explanation:

1 h 25 min×3=3hr 75 min=4hr 15 min(1 hr=60 min)

4 hours  15 minutes

Step-by-step explanation:

3*(1 h 25 min)

3 hours 75 minutes

But 1 hours is 60 minutes

Subtract 60 minutes from 75 minutes and add 1 hour

3 hours +1 hour  75 minutes - 60 minutes

4 hours  15 minutes

repeat the question

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
