Jose travels 130 miles in 150 minutes. how many miles does jose travel in 1 hour?

52 miles

Step-by-step explanation:

We can use a ratio to solve this problem.  Let put miles over time.  We know that 1 hour = 60 minutes.  We need to have the units the same.

130 miles          x miles

    =

150 minutes      60 minutes

Using cross products

130 * 60 = 150 x

Divide each side by 150

130/150 * 60 = 150x/150

52 =x

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
