A hang-glider 25 meters above the ground started to descend (go down) at a constant rate of 2 meters per second. Which equation could be used to determine the height h of the glider after t seconds of descent?

Step-by-step explanation: h = -2t + 25

2t = the distance the glider will pass descending with constant speed of 2 m/s (distance = speed*time)

25 = the initial height that will decrease by the distance that the glider will pass while descending during time t

the answer is b.)

< 1=< 2

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
