Answer:
So the superhero covers 2450 miles in 30 minutes or 1/2 hour
Thus, he/she will cover (2450 x 2) miles in 1 hour
Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.
Hope this helps!

So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute
distance=3 times 21pi
distance=63pi
answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches
