Answer:
95
Step-by-step explanation:
According to given information, machine runs
half an hours to produce 20 tones of ice, and it is also mention that
machine need to run 10 mins to warm up.
half an hours means = 30 mins
total time machine runs is = 30 -10= 20 mins
10 mins is warm up time
So, in 20 mins it produces 20 tones of ice.
And we have to find how much ice in produced if machine runs for 1.75 hours.
Let convert hours to mins
1.75 hours x 60 = 105 mins
We know, 10 mins need for warm up, so actually the machine rans for
105 mins - 10 mins = 95 mins
Now, we have to see weather its a directly proportional or inverse proportional
Ice tones machine time
20 20 mins
x 95 mins
( In 20 mins , machine produce 20 tones of ice, so in 95 mins it produce greater than 20 tones of ice. Direct proportion said that, when one thing is increasing the other thing is also increasing.)
Mathematically,
[tex]\frac{20}{x}=\frac{20}{95}\\[/tex]
x= [tex]\frac{20. 95}{20}[/tex]
x = 95 tones
Result:
When machine runs for 1.75 hours it produces 95 tones of ice.
