Answer:
The answer is 4662.5 kilometers!
Explanation:
- The speed of the Nubian Plate is 2.0 cm per year, which is 2e-5 km per year.
- The speed of the Somali Plate is 2.75 cm per year, which is 2.75e-5 km per year.
- The current distance between these two plates is 5000 km (internet sources).
- After 45 million years, the Nubian plate will have moved 900 km. This is from the calculation as under:
S = V . t
S = (2e-5) . (45,000,000)
S = 900 km --- the new distance between the plates will be 5000 km + 900 km = 5,900 km
- In the same way, the distance which the Somali plate will have moved after 45 million years will be:
S = (2.75e-5) . (45,000,000)
S = 1237.5 km
which is the distance covered by the Somali Plate out of the new distance of 5,900 km.
- So that: (5,900 km - 1237.5 km) will give the new distance between the plates after 45 million years:
4662.5 kilometers
Answer:
Use the rate equation to find the distance that each plate moves. Begin by multiplying speed by time for the Nubian Plate:
distance = speed × time
= 2 cm/yr × 45,000,000 yr
= 90,000,000 cm
The question requires the distance in units of kilometers. Convert the distance using the ratio, 1 km = 100,000 cm:
90,000,000 cm X 1km/100,000 cm = 900km
Next, multiply speed by time for the Somali Plate:
distance = speed × time
= 2.75 cm/yr × 45,000,000 yr
= 123,750,000 cm
The question requires the distance in units of kilometers. Convert the distance using the ratio, 1 km = 100,000 cm:
123,750,000cm X 1km/ 100,000 cm = 1,237.5 km
Finally, subtract the distance traveled by the Nubian Plate from that of the Somali Plate:
1,237.5 km - 900 km = 337.5 km
The Nubian and the Somali Plates will be approximately 337.5 kilometers apart in 45 million years.
