1. if sally can paint a house in 4 hours, and john can paint the same house in 6 hours, how long will it take for both oh them to paint the house together?
Sally can paint the house in 4 hours
The rate at which he can paint the house is 1/4 per hour
John can paint the house in 5 hours
The rate is 1/5 hours
Together the rate is 1/4+1/5=9/20
So they can paint the house in 1/(9/20)=20/9 hours =2.22 hoursTogether = x
1/x = 1/4 + 1/6
1/x = 3/12 + 2/12
1/x = 5/12
5x = 12
x = 12/5 hrs
-->
2 2/5 hrs
2/5 hrs
= 2/5x 60
= 24 min.
2 hours 24 minutes.

Jawab:
7291,67 meter
Penjelasan dengan langkah-langkah:
Diketahui kecepaan motor adalah 105km/24jam
Ditanya seberapa jauh motor bergerak dalam 1 jam 40 menit?
Pertama, ubah dulu satuan kecepatannya menjadi meter/jam
105.000 m / 24 jam = 4375 m/jam
Ubah waktu ke satuan jam
1 jam 40 menit = 1 + 2/3 jam = 5/3 jam
Jika sudah diketahui kecepatannya perjam, tinggal cari jawaban
V=s/t maka s=V.t
s = 4375 x 5/3 = 7291,67 meter
semoga membantu
