Hint: 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.

I 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.

So in this problem if i do 240 divided by 60 i would get the answer 4 for the problem that you should

distance equals rate times time (d=rt) plug in the values and solve

so if i do 136 divided by 17 i should get my answer

Thanks for your help @mathmate

Yes, 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, \(\large yards\div\frac{yards}{minutes}\) =\(\large yards \times \frac{minutes}{yards}\) =\(\large minutes\)
