Question

5. What is the speed (Velocity) of a cyclist who covers 10 km (convert to meters

first!) in 14 minutes and 30 seconds? Remember time must be in seconds first!

Actually Welcome to the Concept of the Kinematics.

Here, we know that, Velocity = Distance / Time,

So here, Distance = 10km = 10×1000 = 10000 metres.

, Time = 14 min 30 sec = 870 seconds,

so now, we get velocity as,

=> V = 10000 ÷ 870 => 11.49 m/s .

Hence, Velocity is 11.49 m/s.
