Question

Can some one please help me ?

Answer 1

$v=\frac{s}{t}\Rightarrow s=vt\\\\v-speed;\ s-distance;\ t-time\\\\v=52mph;\ t=3h\ 15min=3h+\frac{15}{60}h=3h+\frac{1}{4}h=3h+0.25h=3.25h\\\\\\\boxed{s=52mph\times3.25h=169mi}\leftarrow answer$

Answer 2

3 hours and 15 minutes is the same as  3.25 hours.

If the car travels 52miles each hour, and it keeps going and
doesn't stop, then it would travel 52 miles 3.25 times.

3.25 times 52 = 169 miles
