Let the value of Rebecca drove be a

Given Jared drove = 3a

Let's form a equation –

[tex] \sf \longmapsto \: 3a + a = 240[/tex]

There we have a equation!

Let's start solving.

[tex] \sf \longmapsto \: 3a + 1a = 240[/tex]

[tex] \sf \longmapsto \: 4a= 240[/tex]

[tex]\sf \longmapsto \: a = 240/4[/tex]

[tex]\sf \longmapsto \: a = 60(Rebecca \:drove)[/tex]

  • Solving Further

Let's now find the no. of miles Jared drove.

[tex]\sf \longmapsto \: 240 - 60[/tex]

[tex]\sf \longmapsto \: 180( Jared\: drove)[/tex]

So Jared drove –

  • 180 miles

Rebecca drove–

  • 60 miles
