Answer: [tex]\text{Average speed}=49\dfrac{1}{2}[/tex] miles per hour

Step-by-step explanation:

Formula to find the average speed is given by :-

[tex]\text{Average speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]

Given : Distance = [tex]24\dfrac{3}{4}[/tex] miles=[tex]\dfrac{24\times4+3}{4}[/tex] miles

[tex]=\dfrac{99}{4}[/tex] miles

Time =[tex]\dfrac{1}{2}[/tex] hour

Then, [tex]\text{Average speed}=\dfrac{\dfrac{99}{4}}{\dfrac{1}{2}}[/tex]

i.e. [tex]\text{Average speed}=\dfrac{99\times2}{4}=\dfrac{99}{2}[/tex]

i.e. [tex]\text{Average speed}=49\dfrac{1}{2}[/tex] miles per hour
