Answer :

  • It will take 5 hours for Rachel to catch up with Nick.

Explaination :

Here we are given with two equations,

  • f = 7h + 20 (Equation No 1)
  • f = 10h + 5 Equation No 2)

So in order to calculate the number of hours (h). We would simply substitute the value of f in first equation. (i.e., keeping them equal)

>> 7h + 20 = 10h + 5

>> 10h - 7h = 20 - 5

>> 3h = 15

>> h = 15 / 3

>> h = 5
