First, use front end rounding to estimate each answer. Then find the exact answer.A strip of road 3060 feet long is paved in blocks of 17 feet. How many such blocks are there?
A. estimate: 4000 ÷ 20 = 200 blocks; exact: 3060 ÷ 17 = 180 blocks B. estimate: 3000 ÷ 20 = 150 blocks; exact: 3060 ÷ 17 = 180 blocks C. estimate: 3000 ÷ 15 = 200 blocks; exact: 3060 ÷ 17 = 180 blocks D. estimate: 4000 ÷ 16 = 250 blocks; exact: 3060 ÷ 17 = 180 blocks
