Peter Singh notices that the odometer of his car is slow. For a 384 km trip the odometer records only 320 km. If Peter's odometer indicates that he's driven 262.5 km, how far has he actually gone?

Yes, it is directly proportional.

Step-by-step explanation:

Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.

It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
