Answer:

[tex]A : B = 8 : 5[/tex]

Step-by-step explanation:

Given

Truck A

[tex]Distance = 24 miles[/tex]

[tex]Time = 3 hours[/tex]

Truck B

[tex]Distance = 20 miles[/tex]

[tex]Time = 4 hours[/tex]

Required

Determine the ratio of their speeds

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

For A:

[tex]A= \frac{24}{3}[/tex]

[tex]A = 8[/tex]

For B:

[tex]B = \frac{20}{4}[/tex]

[tex]B = 5[/tex]

So, the ratio is:

[tex]Ratio = A : B[/tex]

[tex]A : B = 8 : 5[/tex]
