Javier rode his bike for a total of 40 minutes. the number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch. how many minutes did javier ride after lunch?

Javier rode his bike for a total of 40 minutes.

Let x be the minutes Javier ride after lunch

Let y be the minutes Javier ride before  lunch

The number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch

x = 4 y

The number of minutes he rode after lunch + number of minutes he rode before lunch = 40

x + y = 40

We know x= 4y

4y + y = 40

5y = 40

y = 8

x= 4y so x= 4(8) = 32

Javier ride  32 minutes after lunch
