Will mark most 3. a scuba diver was exploring a reef 32.12 m below sea level. the diver ascended to the surface at a rate of 8.8 m/min. (a) write an equation to model the situation. use the formula d = rt. (b) explain why it is reasonable to write the distance, d, as a positive number. (c) how long did it take the diver to reach the surface?

A. T= d/r
b.  It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something. 
c. T= d/r
T= 32.12 m /8.8 m/min
T= 3.65 min << I hope this helps 

If its 32.12m below sea level then it is -32.12 
-32.12=8.8t.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
