Solution:

I need to use D = rt.

I will divide the situation into two cases.

Case 1

rate = 50

time = 6

Distance = 50(6)

Case 2

rate = 45

time = t

Distance = 45t

Distance for Case 1 = Distance for Case 2.

50(6) = 45t

300 = 45t

Solve for t.

300/45 = t

6.6666666667 = t

I am stuck here.

Note: HOW MANY MORE MINUTES, tells me that traveling at 45 k/hr would have taken 6 hours plus additional minutes. How do I find the additional minutes?
