What is his speed?
Speed = distance/time
Speed = 50m/20s
Speed = 2
...
Brown drives his car at 52
miles per hour
...
How far did he
it take her to do ride 20 miles? travel if he kept driving for 3
hours?
Time = Distance/speed
Distance = speed x time
Time = 20 𝑚𝑖𝑙𝑒𝑠

How long did it take from station A to station B? 3 hours
How far is station A from Station B? 60 kilometers The
speed from station A to station B is:
Speed = distance/time
Speed = 60 km/3h = 20 km/h
