Chris has a two-speed lawn mower. He can mow his entire lawn in "turtle" mode in 1 hour, or 40 minutes in "rabbit" mode. Today, he experimented by mowing half in turtle mode and half in rabbit mode. How many minutes did it take him to mow the lawn?
Kilogram e le 1 ya diapole e ja $<<1*4=4>>4.
Dikgogram di le 2 tsa di banana di ja 2 * 2 = $<<2*2=4>>4.
Dikgogram di le 2 tsa dinamune di ja  2 * 3 = $<<2*3=6>>6.
Ka metlholo o duela 4 + 4 + 6 = $<<4+4+6=14>>14.
