the north american x - 15 rocket - powered aircraft is the world’s fastest manned plane on record. it travels about 7×10³ kilometers per hour. the duck hawk is the world’s fastest bird, traveling at speeds over 3×10² kilometers per hour. which flies faster, the plane or the bird?
Answer
Explanation:
Step1: Expand the speed of the plane
$7\times10^{3}=7\times1000 = 7000$ km/h
Step2: Expand the speed of the bird
$3\times10^{2}=3\times100 = 300$ km/h
Step3: Compare the speeds
Since $7000>300$, the plane is faster.
Answer:
The plane
