Multiply 75 kW by T hours of use = 75T kWh, which is how much energy the motor uses.
Without an equality sign the given expression can't be considered to be an equation and so therefore no solution is possible.
The formula in words is "distance = speed X time". Designating time as t for this instance yields 100 = 75t, or t = 4/3 hours.
i(t)= 900-75t ans: integration(i(t) from 0 to 14 ans:: 375
Answer:75 minutes.Solutionlet the volume of the tank = v, the time required to fill the volume = tv = net flow rate * tv = (v/50 - v/30) * tv= v/75 * t1 = t/75t = 75 minutes.
