Question

It took malcom 6 minutes to walk 500m from the bus stop to the opera house. How fastwas he travelling

Answer 1

$v=\frac{s}{t}\\\\s=500m=0.5km\\\\t=6min=\frac{6}{60}h=\frac{1}{10}h=0.1h\\\\v=\frac{0.5}{0.1}\ km/h=5\ km/h$

Answer 2

Speed = $\frac{distance}{time}$
distance = 500m.
time = 6 min = 360 seconds
speed = $\frac{500}{360}$
speed = 1.38 m/s or $\frac{25}{18}m/s$
