Answer:
1.4 seconds
Step-by-step explanation:
If the red-tailed hawk dives at a constant rate in which its altitude changes by -7 ½ meters in 0.15 seconds, the rate at which it changes its altitude is thus -7 ½ meters ÷ 0.15 seconds = -7.5 meters ÷ 0.15 seconds = -50 meters per second = -50 m/s.
Now, If the red-tailed hawk dives to a depth of -70 meters, the time it will take to cover that distance is t = distance/rate = -70 m/-50 m/s = 7/5 s = 1.4 s
So, it will take the red-tailed hawk 1.4 seconds to dive to a distance of -70 meters.
