The surface of the ground at Drake’s well is 1,200 ft above sea level. To reach oil, Drake first drilled through gravel to a point 1,168 ft above sea level. He then drilled an additional 38 ft through shale. What was the total depth of the well?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
