a plate moving at a rate of 3 cm/year is moving toward a plate that is 1,500 km away. in how many years will the plates collide?\n50,000,000 years\n50,000 years\n5,000 years\n500 years

Answer

Explanation:

Step1: Convert distance to cm

Since 1 km = 100000 cm, then 1500 km = 1500×100000 = 150000000 cm.

Step2: Calculate time

Time = Distance/Speed. Speed is 3 cm/year and distance is 150000000 cm. So time = $\frac{150000000}{3}$ = 50000000 years.

Answer:

50,000,000 years
