eric jogged 3 1/4 miles on monday, 5 5/8 on tuesday, and 8 miles on wednesday. suppose he continues the pattern for the remainder of the week. how far will eric jog on friday?

Respuesta :

Studying the pattern, if we subtract the number of miles of Tuesday to Monday, you'll get 19/8 miles. Subtracting Wednesday to Tuesday, you'll also get 19/8 miles. So the pattern is just adding 19/8 each day. For Thursday, you'll get 10 3/8 miles. On Friday, adding 19/8 miles, Eric jogged a total of 12 3/4 miles.

Answer:

On Friday he jogged

[tex]\frac{51}{4}=12\frac{3}{4}[/tex] miles.

Step-by-step explanation:

Given : Eric jogged 3 1/4 miles on Monday, 5 5/8 on Tuesday, and 8 miles on Wednesday. suppose he continues the pattern for the remainder of the week.

To find : How far will Eric jog on Friday?

Solution :

On Monday he jogged [tex]3\frac{1}{4}=\frac{13}{4}[/tex]

On Tuesday he jogged [tex]5\frac{5}{8}=\frac{45}{8}[/tex]

On Wednesday he jogged 8 miles.

He jogged  from Monday and Tuesday

[tex]\frac{45}{8}-\frac{13}{4}=\frac{45-26}{8}=\frac{19}{8}[/tex]

He jogged  from Tuesday and Wednesday

[tex]8-\frac{45}{8}=\frac{64-45}{8}=\frac{19}{8}[/tex]

He jogs per day is [tex]\frac{19}{8}[/tex]

Now, In Thursday he jogged

[tex]8+\frac{19}{8}=\frac{64+19}{8}=\frac{83}{8}[/tex]

In Friday he jogged

[tex]\frac{83}{8}+\frac{19}{8}=\frac{83+19}{8}=\frac{102}{8}=\frac{51}{4}[/tex]

Therefore, On Friday he jogged

[tex]\frac{51}{4}=12\frac{3}{4}[/tex] miles.
