Kim drives 156 miles from rotherham to london. she has an average speed of 60 miles per hour. she leaves rotherham at 7: 30. does she arrive in london before 10: 00?

Currently, you would ask "How long does it take to get from Rotherham to London?" You would do 156/60, which would be 2.6 hours. 2.6 hours is 156 minutes (2 hours, 36 minutes).
9:36 is when Kim would reach London, so yes.

16 minutes is correct

Igot the answer of 15.8 years.
