If a shark can travel 15 miles per second, then it can go 150 miles in 10 seconds.

Start with 15 m/s. There are 2 units and you need to cancel the seconds to get meters. 

10 seconds has seconds as a unit. This can be used to cancel the sec in the denominator of 15 m/s. This just a little tip I use when I'm unsure about what to do. 

15 m/s x 10 s = 150 meters 

Hope I helped :)
