Question

factory a can produce 25 machines in 20 minutes factory b can produce 10 machines and 15 minutes if both factories produce machines for two hours which factory will produce more machines how many more machines will be produced

Answer 1

$2hours = 2 \times 60 = 120mins$

factory a:

$120 \times \frac{25}{20} = 150 \: machines$

factory b:

$120 \times \frac{10}{15} = 80 \: machines$

150-80=70

so factory a produces 70 more machines than factory b
