We will investigate the distance - speed - time relationship. The following quantities are defined as followed:
[tex]\text{Distance = d ( km ) , Speed = s ( }\frac{km}{hr}\text{ ) , Time = t ( hr )}[/tex]The quantities given are as follows:
[tex]d\text{ = 60 km , s = 25 }\frac{km}{h}[/tex]The distance - speed - time relationship is expressed as:
[tex]s\text{ = }\frac{d}{t}[/tex]We will use the above relationhsip and determine the amount of time taken to cover 60 km at 25km/h speed:
[tex]\begin{gathered} t\text{ = }\frac{d}{s} \\ t\text{ = }\frac{60\text{ km}}{25\text{ }\frac{km}{h}} \\ \textcolor{#FF7968}{t}\text{\textcolor{#FF7968}{ = 2.4 hours}} \end{gathered}[/tex]The time it takes to travel the required distance at the rated speed is:
[tex]\textcolor{#FF7968}{2.4}\text{\textcolor{#FF7968}{ hours}}[/tex]
