Answer:
v = 87.5 km/h
Explanation:
To find the speed of the car you use the following formula:
[tex]v=\frac{x}{t}[/tex] (1)
x: distance traveled by the car = 350km
t: time = 4h
you replace the values of x and t in the equation (1):
[tex]v=\frac{x}{t}=\frac{350km}{4h}=87.5\frac{km}{h}[/tex]
hence, the speed of the car is 87.5km/h
