Given:
Time: 3.5 hrs
Velocity: 120 miles/hour
Now Distance= Speed x Time
Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction.
Hence Distance= Velocity x Time
Distance= 3.5x20=420 miles
These had no leaves or roots, instead they had green photosynthetic stems which served as both anchors in the ground and photosynthetic surface.
They are ectotherms.

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
