The shortest route from Cardiff to London is 120 miles. A lorry is going to take 2 hours travelling using this route.
The lorry actually travels by a different route and this is increased by 20% but still in 2 hours. By how many more MPH than the expected speed does the lorry travel.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30
