A motorcycle is moving at a constant speed of 45km/h how long does it take the motorcycle to travel a distance of 20km?
harina [27]

Answer:

It takes 1600 seconds or \frac{4}{9} hours to travel a distance of 20 km.

Explanation:

Given:

Speed of the motorcycle, v=45\textrm{ km/h}

Distance traveled by the motorcycle, D=20\textrm{ km}

We know that,

Distance = \frac{Speed}{Time}

∴ Time =\frac{Distance}{Speed}=\frac{D}{v}

Plug in 20 km for D and 45 km/h for v. Solve for time.

⇒ Time = \frac{20}{45}=\frac{4}{9}\textrm{ h}=\frac{4}{9}\times 3600=1600\textrm{ s}

Therefore, the time taken to travel a distance of 20 km is 1600 seconds or \frac{4}{9} hours.
