Think about a plan polar researches drill into an ice sheet

Think about a plan.. polar researches drill into an ice sheet. The drill is below the surface at the location shown. The drill advances at a rate of 67m/h. about how many hours will it take to drill to reach a depth of 300m?

1. What equation models this situation

2. What intergers do you need.

Solution

Rate = 67 m/hr

Hours taken to reach 300 metre:

67 metre --in 1 hr

So, 1 mt - 1/67]

Hence for 300 metre -- 300/67 = 4.47 hrs

Let the euqtaion reperseting no. of hours to drill x metre is given as :

T = x/67 hrs

w e have taken the integer which is the speed of drill i.e. 67
