Answer: 7 hours

Step-by-step explanation:

Let the number of hours used be represented by h.

Since a bike cost 8$ plus 3$ Per hour and Ravi spent 29$ for a bike rental.

This can be represented in an equation as:

8 + 3h = 29

Collect like terms

3h = 29 - 8

3h = 21

h = 21/3

h = 7 hours

Ravi rented the bike for 7 hours
