Best ResponseYou've already chosen the best response.6Hint: distance = rate \(\times\) time which makes time = distance \(\div\) rate but check that you are using consistent units, otherwise all quantities must be converted to the same set of units.

Best ResponseYou've already chosen the best response.6I can give an example: Between two stations 240 miles apart, a train travels at 60 mph. How long would the train take before arriving the destination station? Use the formula above: Time = distance / rate = 240 miles / 60 mph =240 / 60 hours = 4 hours. Your question is very similar to the example.

Best ResponseYou've already chosen the best response.0So in this problem if i do 240 divided by 60 i would get the answer 4 for the problem that you should

Best ResponseYou've already chosen the best response.6Yes, the division will give the right numerical value. But it is important to check the units. Since they are both in yards, and the time unit is in minutes, then they are in consistent units. The result will be in minutes. For the units, \(\large yards\div\frac{yards}{minutes}\) =\(\large yards \times \frac{minutes}{yards}\) =\(\large minutes\)
