Jerry jogs the same round trip path everyday. He jogs 0.7 miles to the park and then 0.5 miles from the park to the playground. After getting a drink at the playground, he then jogs back from the playground to his house. He jogs from the playground to the bridge 0.3 miles and then 0.9 miles from the bridge to his house. When Jerry completes his jog, how many miles is he from his house?

is this a trick question, i assume you just add all the number getting 2.4 miles or he is 0 miles away from his house when he completes his jog

Answer:

He will be 0 miles from his house.

Step-by-step explanation:

Since, he jogs the same round trip path.

Thus,

[tex]\text{His final distance from his house }=d_1-d_2[/tex]

Where, [tex]d_1[/tex] = The distance he covered in first trip (towards playground)  

[tex]d_2[/tex] = The distance he covered in second trip (towards house),

In his first trip,

He covered 0.7 miles to the park and then 0.5 miles from the park to the playground.

[tex]d_1 = 0.7 + 0.5 = 1.2\text{ miles}[/tex],

In his second trip,

He covered 0.3 miles to the bridge and then 0.9 miles from the bridge to his house

[tex]d_2 = 0.3 + 0.9 = 1.2\text{ miles}[/tex],

[tex]\text{His final distance from his house }=1.2-1.2=0\text{ miles}[/tex]
