<PRE><B>Question 254382</B>
Given, pablo is driving 40 miles per hour.
after he has driven 30 miles, his brother Ricardo starts driving in the same direction.
Let the speed of Ricardo = x miles per hour.
Time to meet = 5 hours
Distance travelled by Ricardo = 5x
Distance travelled by Pablo   = 5*40+30 = 200+30 = 230
When they meet, both distances are equal.
                  5x = 230
                   x = 230/5
                   x = 46 miles per hour
Therefore the speed of Ricardo = 46 miles per hour.
