Speed = Distance ÷ Time
To find the speed of the car, we first have to identify our values so we can plug our numbers into the formula.
What we know:
Distance = 210 miles
Time = 5 hours
Now that we know our values, we can plug these numbers into our formula.
Speed = 210 ÷ 5
210 ÷ 5 = 42 miles/hr.
Therefore, the speed of the car is 42 mils/hr.
