Can you please help me answer these series of questions

Identify Units NE points [graded] An oil tank is leaking so that its volume of oil V (t) measured in liters at time t measured in hours is V (t) 2 6(10 btjwz. If the number 10 has no units, what are the units of a and 6? Let L denote liters, and let hr denote hours. U 't to L Units of b Average Rate of Change 2 points possible {graded} Based on experimental data, you choose a = 2 and b = 1. An oil tank is leaking so that the volume of oil V (t) at time t measured in hours is V{t) = 2(10 t)5'l2 liters. Find the average rate of change of the volume during the first 5 hours 0
