A man walks to his office at 5 km/hr and then goes back on a rickshaw at 15 km/hr. Find the average speed for the whole journey

In lnY = b1+ b2 ln(L) + b3 ln(K), where b2 + b3 = 1, b2 + b3 – 1 = 0.
Defining c = b2 + b3 -1, b2 = c – b3 +1.
how is ln(Y/L) = b1 + c ln(L) + b3 ln(K/L) derived from
ln(Y) = b1 + (c –b3 + 1 ) ln(L) + b3 ln(K),

Amber completed a 25-kilometer road race in 3 hours. She ran at the same speed and covered the same distance each hour. Between which 2 whole numbers does the distance she ran each hour lie? Draw a visual model to find the distance she ran each hour. You don’t have to do the last part but it’d be great if you did
