Question

Ian travels 225 km in 2.5 hours. At what speed does he travel?

Answer 1

Answer:

Speed = Distance/Time

so, Speed = 225/2.5 Km/hr

                  = 2250/25 Km/hr

                  = 90 Km/hr (ANS)

Answer 2

Concept Introduction:

The speed of an item, which is a scalar number in everyday usage and kinematics, may be defined as the size of the change in direction per unit of time or the size of the change in position over time for an object.

Solution:

Given, Ian travels $225$ km in $2.5$ hours.

We have to find the speed he travels

The speed = $225 / 2.5 = 90$ km/hr

Final Answer:

The final answer is $90$ km/hr
