e = p + 50
time = distance / rate
... 1.6 (1800 / e) = 1800 / p
substituting
... 1.6 [1800 / (p + 50)] = 1800 / p
solve for p, then substitute back to find e and the times
time = distance / rate
... 1.6 (1800 / e) = 1800 / p
substituting
... 1.6 [1800 / (p + 50)] = 1800 / p
solve for p, then substitute back to find e and the times
