If you mean 60 mph then it is 135 miles.

Answer:

135 miles

Step-by-step explanation:

∵ Distance = speed × Time,

Given,

Speed = 30 mph,

Time = [tex]\frac{1}{2}[/tex] hour,

Thus, distance = [tex]30\times \frac{1}{2}[/tex] = 15 miles,

Now, speed = 60 mph,

time = 2 hours,

So, distance = 60 × 2= 120 miles,

Hence, the total distance covered = 15 miles + 120 miles = 135 miles.
