Masalah
Pak anas memiliki tambak ikan mas di hulu sungai yang berada di
belakang rumahnya. Setiap pagi, ia pergi ke tambak tersebut naik
perahu melalui sungai yang ada di belakang rumahnya. Dengan
perahu memerlukan waktu 1 jam lebih lama menuju tambak dari
pada pulangnya. Jika laju air sungai 4km/jam dan jarak tambak dari
rumah 6 km, berapa laju perahu dalam air yang tenang?

Dari Permasalahan yang diberikan di atas, berikut solusi penyelesaiaannya:
Solusi
Dari masalah tadi, kita rumuskan
beberapa pertanyaan:
1) Bagaimana kecepatan perahu saat menuju hulu sungai dan
kecepatan perahu saat Pak Anas pulang?
2) Jika diasumsikan perahu tidak pernah berhenti sebelum sampai
ditujuan, apa yang dapat kamu simpulkan dari keadaan perahu?
3) Coba temukan bentuk perasamaan kuadrat dalam langkah
pemecahan masalah tersebut?
next
adalah kecepatan air sungai dengan Va = 4 km/jam
adalah kecepatan perahu kehulu
adalah kecepatan perahu saat pulang
adalah kecepatan perahu dalam air tenang
adalah waktu yang diperlukan menuju Tambak
adalah waktu yang digunakan menuju rumah (pulang)
adalah jarak tambak dari rumah Pak Anas
Misalkan: Next
Bagaimana kecepatan perahu saat pergi kehulu dan saat menuju hilir
(pulang)?
Kecepatan perahu saat menuju hulu sungai menentang kecepatan air
dan saat Pak Anas pulang, kecepatan perahu searah dengan kecepatan
air sungai mengalir. Sehingga, Jika dimisalkan = x km/jam maka
Diasumsikan perahu tidak pernah berhenti sebelum sampai di tujuan
berarti,
Next
Kecepatan perahu di air tenang adalah .
Nilai tidak berlaku sebab kecepatan perahu bergerak maju selalu
bernilai positif.
Sehingga, laju perahu dapat dicari,
