A transit train from Boston to New York and a transit train from New York to Boston departed at the same time, 3:00 PM. The distance between New york station and Boston station is 280 miles. The speed of the transit train is 80 miles per hour. The speed of the passenger train is 80 miles per hour. What time will the two trains pass eachother?

is there any attachment? what are the equations?

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
