Answer:
-1212 feet/min * 412 min = -499314 feet
Step-by-step explanation:
if you have a speed, or in this case velocity since the measurement has a definite direction, and time you can multiply them together to get the distance. Some easy examples, 10 feet per second for 1 second is 10 feet, hopefully that logically makes sense as well. i you are going 10 feet in 1 second, then after 1 second you went 10 feet. after 2 seconds it's 20 seconds and so on
Here we have -1212 feet per minute for 412 minutes. just to establish things, 1 minute would be -1212 feet, here the negative means below the surface, sometimes measurements will have that. Anyway, 2 minutes would get -2424, and so on. So it should make sense to multiply them.
-1212 * 412 = -499314
With units, you also have to pay attention to what might cancel out. You treat different units like variables. so -1212feet per minute looks like -1212 feet/min where feet and min are basically variables. Similarly 412 minutes is 412 min. So if you picture multiplying these, you get -1212 feet/min * 412 min. In this scenario the mins cancel each other out, since everything s being multiplied. so like if you had x/y * y you would just get x, or 2/3 * 3 gets just 2. So this is another way to know what to multiply by.
feet/min has min in the denominator and we want feet, so we need to multiply by something that just has min as its units. Anyway, that let's you know it's -499314 feet
