Question

The graph shows the rate at which water is pumped from a storage tank. Approximate the total gallons of water pumped from the tank in $24$ hours.

• A. $600$
• B. $2400$
• C. $3600$
• D. $4200$
• E. $4800$

Answer 1

The correct option is C $3600$

Amount of water pumped =Area of triangle + Area of rectangle +$\Delta x$

$=\frac{1}{2}\times (250-50)\times 24\times 50\times 24+\Delta x=3600+\Delta x\cong 3600$

Hence the correct answer is $3600$
