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.
