Answer 2

Answer:

$The \: speed \: of \: cyclist \: is \: 10 m/s \: \: or \: 36.05 km/h.$

Step-by-step explanation:

$It is given that,$

$Distance covered by the cyclist, d = 1.5 km = 1500 m$

$Time, t = 2.5 minutes = 150 s$

$Total \: distance \: covered \: by \: an \: object \: divided \: by \: total \: time \: taken \: is \: called \: its \: speed. \: It \: is \: given \: by : \: </p><p>$

$v=\dfrac{1500\ m}{150\ s}v= </p><p>150 s</p><p>1500 m$

$v = 10 m/s</p><p></p><p>Time in hours, t = 0.0416 h$

$Speed, v=\dfrac{1.5\ km}{0.0416\ h}v= </p><p>0.0416 h</p><p>1.5 km$

$v = 36.05 km/h$

$So, the speed of cyclist is 10 m/s or 36.05 km/h. Hence, this is the required solution.$
