Question

The formula for determining how long a hike will take is t=1/2(d+h) , where d is the distance in miles and h is the elevation gain in thousands of feet.
Solve for h.

A. h=2d-t

B. h=1/2t-d

C. h=2t-d

D. h=(t-d)/2

Answer 1

Answer is c.

t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h

Answer 2

ANSWER IS C, THE WORK IS UP THERE ^^^
