Question

A SUBMARINE DESCENDS FROM THE SURFACE OF WATER OF THE RATE OF 4 MILLI CENTIMETER . AT THIS RATE , HOW LONG DOES IT TAKE FOR THE SUBMARINE TO REACH (-248 METER) BELOW THE SEA LEVEL

Answer 1

Step-by-step explanation:

Given A SUBMARINE DESCENDS FROM THE SURFACE OF WATER OF THE RATE OF 4 M/S. AT THIS RATE , HOW LONG DOES IT TAKE FOR THE SUBMARINE TO REACH (-248 METER) BELOW THE SEA LEVEL

• So speed of the submarine is at the rate of 4 m.
• So speed will be 4 m / s
• So the distance will be 248 m
• We need to find the time the submarine would take to reach below sea level.
• We have Speed = Distance / Time
•                 Time = Distance / Speed
•                      Time = 248 m / 4 m/s
•                        Time = 62 Secs
• Therefore it would take the submarine 62 seconds to reach 248 m below the sea level
