Answer:

A: 5 miles

B: 9 mph

Step-by-step explanation:

A:

since the speed is constant, in half an hour, Mike would travel 5 miles.

this is because:  10 miles/1 hour  = 5 miles / 0.5 hours    (multiply top and bottom by 1/2)

B:

[tex]\frac{18 miles}{2 hours}[/tex] = [tex]\frac{9 miles}{1 hour}[/tex] = 9 mph
