A meteorite crashes in the Indian Ocean, creating circular waves that move at 20m/s. If the nearest island is 2 km north and 6 km east of the spot where the meteorite landed, how many seconds will it
take for the waves to first reach the island? (careful with units - round your answer to one decimal point)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
