David drives 67.5 miles in 45 minutes. If he drove three hours in total at the same rate, how far did he go?

270 miles

Step-by-step explanation:

45 minutes = 67.5 miles

1 minute = 67.5 ÷ 45 = 1.5

3 hours = 60 x 3 = 180 minutes

180 minutes = 1.5 x 180 = 270

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
