Question

Babar drives 300km at an average speed of 80km/h calculate the time

Answer 1

`3hr\text{s45min}`

Step-by-step explanation

Recall, that the speed is calculated using the formula;

`Speed=(distance)/(time)`

Given;

`\begin{gathered} speed=80kmhr^(-1) \\ distance=300km \end{gathered}`

Substitute the values into the formula;

`\begin{gathered} Speed=(d\imaginaryI stance)/(t\imaginaryI me) \\ 80=(300)/(t) \\ \end{gathered}`

Solve for t;

`\begin{gathered} 80=(300)/(t) \\ 80t=300 \\ t=(300)/(80) \\ =3.75 \\ 0.75*60=45min \end{gathered}`

Therefore, the time taken is 3hours, 45minutes
