x km/jam --> 45 menit = 3/4 jam = 0,75 jam
Perbandingan berbalik nilai
x/60 = 1,2/0,75
0,75x = 60 × 1,2
0,75x = 72
x = 72 : 0,75
x = 96 km/jam
b. 32 pekerja --> 72 hari
x pekerja --> 48 hari
Perbandingan berbalik nilai
x/32 = 72/48
x/32 = 3/2
2x = 3 × 32
2x = 96
x = 96 : 2
x = 48 pekerja
Banyak tambahan pekerja
= 48 - 32
= 16 pekerja
c. Sisa hari setelah 10 hari
= 22 - 10
= 12 hari
Sisa hari agar target gedung selesai dibangun tercapai
= 12 - 6
= 6 hari
12 hari --> 20 pekerja
6 hari --> x pekerja
Perbandingan berbalik nilai
6/12 = 20/x
1/2 = 20/x
x = 2 × 20
x = 40 pekerja
Banyak tambahan pekerja
= 40 - 20
= 20 pekerja
