We have that Jamir is training for a race and is running laps around a field:

• The distance around the field is 450 yards (per lap).

,

• He needs to run at least 4 miles.

1. Now we can proceed as follows to find the number of laps Jamir needs to run as follows:


\begin{gathered} 1\text{ Mile}=1760.0065617yards \\ \\ 4\text{ Miles=}4(1760.0065617yards)=7040.0262468yards \end{gathered}

Then we have that Jamir needs to run about 7040.0262468 yards.

2. Since the distance around the field is 450 yards (per lap), then we have:


7040.0262468yards*(1lap)/(450yards)=15.6445027707laps

Therefore, in summary, Jamir needs to run about 15.64 laps to run at least 4 miles (almost 16 laps - if we round the result to the nearest whole number).
