Question

A scuba diver descended at a rate of 3 1/2 yards every 5 minutes from the surface of the water. What was the depth of the diver after 30 minutes?

Answer 1

In the above Question, the following information is given -

A scuba diver descended at a rate of 312 yards every 5 minutes from the surface of the water .

To find -

What was the depth of the diver after 30 minutes?

Solution -

Here ,

A scuba diver descended at a rate of 312 yards every 5 minutes from the surface of the water .

So,

Let us assume that the surface of the water has 0 depth i.e , is at sea level .

Now ,

Refer to the above attached figure.

Here ,

Every 5 minuites , this driver descends a length of 312 yards .

Now ,

In 30 minuites ,

Length descended by the diver -

=> 312 × 6 yards

=> 1892 yards .

Thus , the diver descends a length of 1892 yards below sea level in 30 minuites .

This is the required answer.

________

Additional Information -

1 yard = 0.914 metres approximately .

1 metre = 1.094 yards approximately .

Speed = [ Distance / Time ]

Velocity = [ Displacement / Time ]

Displacement < Distance

1 minuite = 60 seconds
