Answer:
62.5 km/hr
Explanation:
Speed can be found by dividing the distance by the time.
s=d/t
We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:
• d=125 km
• t= 2 hr
Substitute the values into the formula.
s= 125 km/ 2 hr
Divide
s= 62.5 km/ hr
The speed of the car is 62.5 kilometers per hour.
