Question

1. translate gary’s speed of 24 kilometres per hour as a speed in metres per second.

Explanation:

Step1: Convert kilometers to meters

We know that 1 kilometer = 1000 meters, so 24 kilometers = \(24\times1000 = 24000\) meters.

Step2: Convert hours to seconds

We know that 1 hour = 3600 seconds.

Step3: Calculate speed in meters per second

Speed is distance divided by time, so the speed in meters per second is \(\frac{24000}{3600}=\frac{20}{3}\approx 6.67\) (rounded to two decimal places).

Answer:

\(\frac{20}{3}\) (or approximately \(6.67\)) metres per second
