    Here, we must set up a proportion.

    90/x = 45/1

    Now, cross multiply.

    90*1 = 45*x Multiply each

    90 = 45x Our result.

    Now, divide 45 by both sides to isolate the variable.

    45x/45 = 90/45 Divide by both sides.

    x = 90/45 Now divide

    x = 2 x equals 2

    Now that we know that x equals two, we also know how long it took him to drive. Add units to our answer.

    Final answer: It took us 2 hours
