Answer:

70 km/h

Step-by-step explanation:

A car is travel 210 km in 3 hours.

Distance, d = 210 km

Time, t = 3 hours

We can find the speed of the car. The speed of an object is equal to the total distance divided by time taken.

v = d/t

Substitute the values,

[tex]v=\dfrac{210\ km}{3\ h}\\\\v=70\ km/h[/tex]

So, the required speed of the car is 70 km/h.
