He will spend RM 28.44.

Step-by-step explanation:

Each mile has 1.61 km.

So the distance, in miles, is given by:

$\frac{330}{1.61} = 205$

For 60 miles, he uses 4.5 liters. So, for 205 miles, he will use:

$\frac{205*4.5}{60} = 15.375$

For the trip, he uses 15.375 liters. Each liter costs RM 1.85. So he will spend:

15.375*1.85 = 28.44

He will spend RM 28.44.
