Answer 1

Answer: a. 50,000,000 years

Step-by-step explanation:

Answer 2

Answer:
`5* 10^7\ \text{years}`

Step-by-step explanation:

Given

A Planet is moving at a rate of 3 cm/year

distance between planets is 1500 km

and 1 km=1000 m

1 m=100 cm

No. of years required to cover 1500 km=
`(1500* 1000* 100)/(3)=5* 10^7\ \text{years}`
