If (M(t)=62+5t) and (N(t)=142-5t), when will (M(t)) be (20) more than (N(t))?

Answer and explanation

Correct answer: \(t=10\)

“20 more” means \(M(t)=N(t)+20\). Thus, \(62+5t=142-5t+20\), or \(62+5t=162-5t\). This gives \(10t=100\), so \(t=10\). At \(t=8\), the difference is 0, so it is a close but incorrect option. Exam tip: for “more than” questions, equate the larger quantity to the smaller quantity plus the stated difference.
