As mercury revolves around the sun, it travels at a rate of approximately 30 miles per second. convert this rate to miles per minute. at this rate, how many miles will mercury travel in 4 minutes?

30 miles per second times 60 seconds = 1,800 miles per minute.
To find out for 4 minutes, now we multiply 1,800 miles times 4 which = 7,200 miles.
In 4 minutes, Mercury will travel 7,200 miles.

The correct answer is -20y

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
