Answer:

  • 3s - 7.5 miles

Step-by-step explanation:

Given

  • The speed of car1 is s,
  • The speed of car2 is 5 less than s,
  • Time is 1.5 hrs.

Solution

Distance equation:

  • Distance = speed * time

If cars move in opposite directions their speeds add up, then the distance between them after 1.5 hours is:

  • (s + s - 5)*1.5 =
  • (2s - 5)*1.5 =
  • 3s - 7.5

Answer:

After 1.5 hr, they are 3s - 7.5 mi away.

Step-by-step explanation:

Forming the expression,

→ 1.5 × (s + s - 5)

Now the required solution will be,

→ 1.5 × (s + s - 5)

→ 1.5 × (2s - 5)

→ 1.5(2s - 5)

→ 3s - 7.5

Hence, answer is 3s - 7.5 miles.
