Step-by-step explanation:

The equation for the growth of people = 308.7 (1097) ^x

The equation for the growth of vehicles = 246 (1155) ^x

If the number of both are equal tham

308.7 (1097) ^x=246 (1155) ^x

Dividing both sides by 246

1.254878 (1097) ^x = (1155) ^x

Dividing both sides by (1097) ^x

1.254878 = (1155:1097) ^x

X=4.406 decades

X=44 years
