Please help me with the day by hour and variance, thank you very much

Oriole Company manufactures toy trucks. Orders for 8,700 trucks were received during March, with deliveries scheduled evenly throughout the month of April. Trucks are produced simultaneously in 9 manufacturing cells. Time available for production in each cell is 7 hours per day for 21 days during March. Your answer is correct. Calculate the takt time. (Round answer to 1 decimal place, e.g. 15.2.) Takt time (9. 12) minutes per truck x Your answer is incorrect. Try again. At the end of the first hour of a day's production, one cell had completed 6 good trucks, including one truck that was reworked. Calculate the day-by-the-hour results and the variance. (Round answers to 1 decimal place, e.g. 15.2. Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).) Day-by-the-hour X [1.8 trucks per hour Variance 0.2 trucks Your answer is correct. At the end of the first hour of a day's production, one cell had completed 6 good trucks, including one truck that was reworked. Calculate the first time through (FTT) rate. (Round answer to 2 decimal places, e.g. 15.26%.) First time through rate 183.33%
