300 calories are burned for 60 minutes

Solution:

Given that, Antonio burns 75 calories for every 15 minutes he rides his bicycle

To find: calories burned if he rides his bicycle for 60 minutes

From given information,

For every 15 minutes, 75 calories is burned

Therefore, for 1 minute,

$1 \text{ minute } = (75)/(15) = 5 \text{ calories }$

So in 1 minute, 5 calories are burned

We have to find the calories burned for 60 minutes

Let "x" be the calories burned for 60 minutes

1 minute = 5 calories

60 minutes = x calories

This forms a proportion and we can solve the sum by cross multiplying

$x * 1 = 5 * 60\\\\x = 300$

Thus 300 calories are burned for 60 minutes
