Respuesta :

44 because 1.00 -3.00 = 2.00
208miles-120miles=88.
88/2 because it is measured in kmper hour so we need one hour so it is 44

Answer:

The constant speed is 44 miles per hour

Step-by-step explanation:

We have the following details.

Point A

[tex]t_{1}= 1.00\\x_{1}= 120[/tex]

Point B

[tex]t_{2}= 3.00\\x_{2}= 208[/tex]

The speed in this case is defined as

[tex]s=\frac{\Delta x}{\Delta t}[/tex]

Where [tex]\Delta x=x_{2}- x_{1}[/tex] and [tex]\Delta t = t_{2}- t_{1}[/tex]

Replacing all values, we have

[tex]s=\frac{208-120}{3.00-1.00}=\frac{88}{2}=44[/tex]

Therefore, the constant speed is 44 miles per hour, which means the car travels 44 miles every hour.
