Laura will take \frac{1}{4} hour or 15 minutes to catch up with Tony.

<u><em>Explanation</em></u>

Distance between Tony and Laura is \frac{1}{2} miles and the difference of their speeds = (7 - 5 ) mph = 2 mph

For catching up with Tony, Laura needs to travel that \frac{1}{2} miles with the speed of 2 mph

As, Distance = speed × time

So,  \frac{1}{2} = 2 × t

⇒ t = \frac{\frac{1}{2}}{2} = \frac{1}{4} hour = \frac{1}{4} × 60 minutes = 15 minutes

That means, Laura will take \frac{1}{4} hour or 15 minutes to catch up with Tony.
