It takes a boat going upstream 3 hours to cover the same distance, as it would cover in 2 hours going downstream. What is the speed of the boat if the speed of the current is 3 kilometers per hour?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
