Bj's Math Question

13. A submarine was cruising at a depth of 153 m. It then rose at 4.5m/min for 15 min.

a) What was the submarine's depth ate the end of this rise?

The depth of the submarine is 67.5m

.

What I did was I multiplied 4.5 by 15

- 4.5

x1 5

67.5

b) If the submarine continues to rise at the same rate, how much longer will it take to reach the surface.

It will take the 19 min to take the submarine to reach the surface.

1)What I did was I to subtracted the depth of the submarine to the end of it's rise.

2)Then I multiplied 19 min to the min of the end of it's rise.

3)Finally, I subtract 85.5 by 85.5.

1) 153

-67.5

85.5

2) 1 9

x 4.5

85.5

3) 85.5

- 85.5

The Rules of finding the decimal/fraction between decimals

Rules

1) Imagine as many zeros as you want after the least place value after decimal.

2)Put a digit in the next place value.

3) Change decimal into a fraction...... simplify if possible.

Example:

Find the fraction between

0.452 and 0.453
