Exercise 61 Page 28

To find the number of miles jogged around the track, we have to multiply 0.25 by the number of laps.

F

Practice makes perfect

Let's investigate each of the given statements one at a time.

Option F

It is given that Lane 1 is 0.25 miles long and we are jogging 6 times around the track. To calculate the total distance, we need to multiply 6 by 0.25. 6*0.25=1.5 mi

Option G

Let's start by calculating the distance of jogging 5 times around the track in Lane 1. We can do it by multiplying 5 by the length of the track. 5*0.25=1.25 mi Next, since we are also jogging to the track, we need to add that a distance of 0.5 miles. 1.25+0.5=1.75 mi

Option H

First, we can calculate the distance of jogging 3 times around the track by multiplying 3 by the length of the track. 3*0.25=0.75 mi Now, we have to add the distance we are jogging to and from the track, which is 0.5 miles both times. 0.5+0.75+0.5=1.75 mi

Option I

Jogging 8 times around the track is longer than jogging 6 times around, which is option G. Since we are asked to find the shortest jog, there is no point in calculating the distance of this jog.

Conclusion

Let's compare the distances of the jogs from the first three options. OptionF:& 1.5mi OptionG:& 1.75mi OptionH:& 1.75mi As we can see, the shortest jogging distance is option F.
