A tram goes over the bridge every 8 minutes. The first tram goes over the bridge at 6am. What is the next time that the tram goes over the bridge on the hour?

Think this way.

60 min/8 min

= 7.5

------That tells you something right there!

120 min/8 min

= 15

------15 8's in two hours, so...,

8:00 AM

======The next time the tram goes over the bridge on the hour.
