Mr.Ronald travelled 5/8 of his journey in 150 min at an average speed of 82 km/h. What was the total distance of his journey?

    distance=(rate)*(time)

    use the proportions method.

    5/8 = [(150min [convert mins to hours! so that you'd be able to cancel the hours])(82km/h)]/[total distance]

    solve for total distance.

    Distance = Velocity * Time

    150 min. = 2.5 hours

    5/8D = (82 * 2.5)

    I'll let you do the calculations.
