Answer

Answer:

C. 10

Explanation:

Step1: Identify engine speed

The digital dashboard shows an engine - speed of (6.5\times100 = 650) rpm.

Step2: Interpolate from the table

The table has engine - speed values of 500 rpm with a flow rate of 1.0 gpm and 750 rpm with a flow rate of 2.5 gpm. Since 650 rpm is closer to 750 rpm, and we can also note that the speed on the left - hand side of the dashboard is 6.5 mph. Looking at the right - hand table for flow rate based on engine speed, when the engine speed is in the range around 650 rpm (by interpolation or just observing the trend), the closest value to the flow rate for an engine speed around 650 rpm is 10.0 gpm (as the engine speed of 650 rpm is between 500 rpm and 750 rpm, and the flow rate is increasing linearly in this small range). So the approximate current flow rate is 10 gpm.
