A submarine descends 1/120 mile every minute. Write a product of three or more rational numbers to represent the change in the submarines elevation after 3 hours. Then find the value of the product and explain what it represents.

9514 1404 393

  (1/120 mile/min)(60 min/h)(3 h)

  1.5 mile

  the increase in depth after 3 hours

Step-by-step explanation:

The rate is given in terms of miles per minute. To find the elevation after 3 hours, we need a conversion from minutes to hours. One possible product is ...

  (1/120 mile/min)(60 min/h)(3 h)

The value of this product is ...

  (1·60·3)/(120·1·1) mile = 1.5 mile

The value represents the increase in depth after 3 hours.

12cm

the answer is d

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
