Solving which gives t=2. Substituting the value of t in 40(3-t), we get the distance travelled by bus is 40 miles. Alternatively, we can add the time and equate it to 3 hours, which directly gives the distance. d/30 + (100-d)/40 = 3. Solving which gives d = 60, which is the distance travelled by train. 100-60 = 40 miles is the distance
