Answer:
To determine whether a calculated car speed of 290 km/h is reasonable based on the equation of distance = speed × time, we need more information. The equation distance = speed × time relates three variables: distance, speed (velocity), and time. To assess the reasonableness of a calculated speed, we need values for at least two of these variables.
If you have the values for distance and time, you can use the equation to calculate the speed:
Speed (km/h) = Distance (km) / Time (hours)
Without values for distance and time, it's impossible to evaluate whether a calculated speed of 290 km/h is reasonable or not. To assess its reasonableness, you need to provide additional information or context regarding the specific situation or problem you're dealing with.
