Question

He climbed up at a rate of 4 meters per second. After 3 seconds, he was 13 meters below the edge of the volcano. How far was Zane below the edge of the volcano when he started climbing? In total, how long did it take Zane to reach the edge of the volcano?

Answer 1

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
