1170.94 – Total Tree Growth

There are 351 trees in the Arboretum. Of these, 176 are conifers. Over three months, the conifers grew an average of 3 inches in height, and the deciduous trees grew an average of 0.75 inches. If all the trees were to be laid, lengthwise, in a straight line after this growth, how much longer would that line be than it would have been 3 months before?

Solution

There are 176 conifers out of 351 trees, so there are 175 deciduous trees. The conifers averaged 3 inches of growth each; that’s 176×3 in=528 in176 \times 3 \ \inch = 528 \ \inch. The deciduous trees averaged 0.75 inches; that’s 175×0.75 in=131.25 in175 \times 0.75 \ \inch = 131.25 \ \inch. The total is 659.25 inches, or about 54 feet 11 inches, nearly 55 feet. Go hug a tree!
