<h3><u>Answer.</u> 12</h3>
we are given
climbing rate =4m/s
after 3 second ,
he climbed =4*3=12m
and
he was 13 meters below the edge of the volcano
so, total distance is 12+13=25m
so, distance of the edge of the volcano when he started climbing is 25m.....Answer
speed=4m/s
time = distance / speed
time =25/4
time is 6.25sec......Answer
An expression becomes an equation by adding an equal sign to the end of the expression and if there's a number on the other side of the equation. For example, 4+3 becomes an equation if you put 4+3=7. Or, 4+3=2+5. Good luck!
There are a few ways to get -15 to equal -3 one is put +12
-15+12=-3
Or putting /5
-15/5=-3
