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:

Explanation:

We have the following details.

$t_(1)= 1.00\\x_(1)= 120$

$t_(2)= 3.00\\x_(2)= 208$

The speed in this case is defined as

$s=(\Delta x)/(\Delta t)$

Where
$\Delta x=x_(2)- x_(1)$ and
$\Delta t = t_(2)- t_(1)$

Replacing all values, we have

s=(208-120)/(3.00-1.00)=(88)/(2)=44

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