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
The answer is option B. 11/12 = (13 3/4) /15
it could be considered a true proportion if both are equal in values.
In order to find this, you need to cross multiply the numerator and the denominator in all of those options and find which give the exact result.
11 x 15 = 13 3/4 x 12
165 = 165
The answer is 11/4 or 2 3/4
