**Answer:**

525 km

**Step-by-step explanation:**

Let d represent the distance to the town. Let s represent the nominal speed of the car. The relation between time, speed, and distance is d = st.

t1 = d/s

t2 = d/(s+15)

t1 : t2 = 6 : 5 . . . increasing the speed reduces the time

Substituting for t1 and t2, we have ...

(d/s)/(d/(s+15)) = 6/5

(s +15)/s = 6/5

1 +15/s = 1 +1/5

s = 5·15 = 75 . . . . nominal speed in km/h

__

Decreasing the speed increases the time.

d/75 +(105/60) = d/(75-15)

d(60/75) +105 = d . . . . . . multiply by 60

105 = d/5 . . . . . . . . . . . subtract 4/5d

525 = d . . . . . . . . . . multiply by 5

**The distance traveled by the car is 525 km**.
