Provide an appropriate response.Consider the following: Henry drove his new car for y minutes at x mph. Since d = rt, Henry drove his new car a total of (xy) miles. Is this correct? Explain.

What will be an ideal response?


No, it is not correct. When using the formula d = rt (distance = rate × time), you must make sure that all the units correspond. When expressing rate in miles per hour (mph), you should express time in hours, not minutes. Replace y minutes with  hours to calculate a distance of  (Alternatively, convert the rate to miles per minute and calculate
