The small submarine is -1,320 feet in relation to sea level. the submarine needs to be 180 feet below sea level in 60 minutes. how far must the submarine travel?

The first submarine needs to travel at 19 feet per minute to rise to –180 feet. The second submarine needs to travel at 21 feet per minute to rise to –180 feet. The second submarine must travel 2 feet per minute faster than the first.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it
