The Flash just realized somebody is following him, which doesn't happen often. He stops to watch, trying to gauge how fast his pursuer is going. In 4 seconds, the guy goes 1,120 meters... not traveling at the speed of light like Flash, but the new guy seems to be going the speed of sound.

• 1120 meters divided by 4 seconds

• Velocity

• 280 m/s

• Acceleration

• 280 m/s²

• Where are these numbers coming from?

• 280 m/s towards Flash

• Speed

Quicksilver just saw a blur go past him (that doesn't happen often). From what he saw, the being went 9, 000, 000 meters in 3 seconds. Then he started the chase. Who else is possibly this fast?

• 9,000,000 meters divided by 3 seconds

• Velocity

• 3, 000, 000 m/s away from Quicksliver

• Speed

• 3, 000, 000 m/s²

• Acceleration

• 3, 000, 000 m/s

• Where are these numbers coming from?
