David drove a distance of 187km, correct to 3 significant figures. He used 28 litres of petrol, correct to 2 significant figures.
The petrol consumption of a car, in km per litre, is given by the formula.
c=d/p
by considering bounds, work out the value of c for David's journey.

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
