Question

3. Ariya and Han are biking in the same direction on the same path.

Priya started riding a half hour before Han. If Han has been riding for thours, how long has Priya been riding?

Answer 1

Priya has been riding for t + 0.5 hours, where t is the number of hours Han has been riding.

Step-by-step explanation:

If Han has been riding for t hours, then Priya, who started riding a half hour before Han, has been riding for t + 0.5 hours.

This is simply a matter of adding the half hour head start Priya had to the time Han has been biking. It's important to ensure units are consistent; here, we are working with hours, so half an hour is expressed as 0.5 hours.
