It took a truck, which is moving at 60 mph, 8 hours to get from Boston to Washington DC. How long will it take a car to get from Boston to Washington DC, if it travels at 75 mph?

Respuesta :

For this case we have that by definition the time is given by:

[tex]t=\frac{d}{v}[/tex]

Where the variable "d" represents the distance and "v" represents the speed.

So, first we need to know the total distance:

[tex]d=(v)(t)[/tex]

[tex]d=(60)(8)[/tex]

[tex]d=480 mi[/tex]

Then, the time for 75mph is given by:

[tex]t=\frac{480}{75}[/tex]

[tex]t=6,4[/tex]

Answer:

6,4 hours

Answer:

6.4 hours

Step-by-step explanation:

60*8/75=

480/75=

6.4
