Two cars start from the same point on flat ground. The first car drives off directly north at 25 m/s. Two seconds later the second car drives off directly east at 20 m/s. After how many seconds are they 1km apart?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
