The distance covered by a car is 453 km in 8.7 hr. Find the estimated speed of the car.
47 km/hr
49 km/hr
50 km/hr
54 km/hr
Speed is calculated by dividing total distance by total time. Dividing 453 km by 8.7 hr gives approximately 52.06 km/hr. Among the choices, 50 km/hr is the closest estimate.
Using the formula for speed, which is distance divided by time, the estimated speed is 453 divided by 8.7. This calculation gives a result of approximately 52.07 km/hr. Rounding to the nearest ten gives an estimated speed of 50 km/hr, which matches the expected result.
