2. John drove for 3 hours at a rate of 50 miles per hour and for 2 hours at 60 miles per hour. What was his average speed for the whole journey?
Jawab:
Penjelasan dengan langkah-langkah:
(50x3+60x2)/(3+2)
150+120/5
270/5
54
So his avarage speed for the whole journey was 54 miles/hour
Penjelasan dengan langkah-langkah:
average speed = (3x50)+(2x60) / (3+2)
= 270/5 = 54milesperhour
3. Express 3 hours 12 min in hours as a decimal
Answer:
3.2 hours (three point two hours)
____________________Explanation:
Express 3 hours 12 min in hours as a decimal (nyatakan 3 jam 12 menit dalam jam dalam bentuk desimal)
change 12 min to hours (ubah 12 menit ke jam)= 12 min ÷ 60
= 0.2 hours
add 3 hours to 0.2 hours (jumlahkan 3 jam dengan 0,2 jam)= 3 hours + 0.2 hours
= 3.2 hours.
Final answer :
Therefore, 3 hours 12 min in hours as a decimal is 3.2hours

→ 3 ekor kambing memakan 3kg rumput dalam waktu 3 jam. Berapa lama waktu yang dibutuhkan 2 kambing untuk memakan 2 kg rumput?
Jawab :
3 kambing → 3 kg → 3 jam
2 kambing → 3 kg → a
³/₂ = a/3
2a = 9
a = ⁹/₂ jam
Maka :
2 kambing → 3 kg → ⁹/₂ jam
2 kambing → 2 kg → b
³/₂ = (⁹/₂) / b
3b = 9
b = ⁹/₃
= 3 jam
Jawaban ☞ 3 hours (C)

13. If a cyclist in the Tour de France traveled southwest a distance of 12,250 meters in one hour, what would the velocity of the cyclist be?
Jawaban:
Kita tahu bahwa kecepatan diartikan sebagai laju jarak yang ditempuh per satuan waktu, jarak / waktu, serta memiliki kecepatan dan arah. Di sini, kita diberi tahu bahwa dalam waktu satu jam, pengendara sepeda menempuh jarak 12.250 meter. Jadi, kami tahu bahwa:
t = 1 jam
d = 12.250 m
Kita juga tahu bahwa ada 60 detik dalam satu menit dan 60 menit dalam satu jam, dan kita mungkin menginginkan kecepatan dalam satuan meter per detik, m / s. Jadi, mari gunakan persamaan yang relevan dan masukkan angka dan konversi unit kita:
v = d / t
= 12.250 m * 1 jam * 1 menit
1 jam 60 menit 60 detik
= 3.403 m / s barat daya
Jika Anda perlu melaporkan arah dalam satuan derajat atau radian, buat timur 0 ° atau 0 radian, dan putar 45 ° atau Ï€ / 4 radian 5 kali berlawanan arah jarum jam untuk mendapatkan 225 ° atau 5Ï€ / 4 radian.
