    Time that will be taken at speed of 45 miles/hr is 1.8 hrs

    Step-by-step explanation:

    Step 1: Given the speed of the journey = 54 miles/hr and time = 1.5 hours. Find the distance of the journey using the speed formula.

    Distance = Speed * Time

    = 54 * 1.5 = 81 miles

    Step 2: Calculate the time taken for this journey given speed = 45 miles/hr

    TIme = Distance/Speed

    = 81/45 = 1.8 hrs
