Misalai 4 na matsakaicin gudu da matsakaicin gudu

1. Mota ta yi tafiya kai tsaye zuwa gabas na mita 100 cikin daƙiƙa 4 sannan ta yi tafiya kai tsaye zuwa yamma na mita 50 cikin daƙiƙa 1. Ka tantance matsakaicin gudu dan matsakaicin gudu motsi.
Tattaunawa

Nisa = mita 100 + mita 50 = mita 150
Adadin ƙaura = mita 100 – mita 50 = mita 50 kuma alkiblar ƙaura tana gabas.
Jimlar lokaci = daƙiƙa 4 + daƙiƙa 1 = daƙiƙa 5.
