Question

Anita was driving at a speed of 85.6 km per hour. If the road had a speed limit of 55 km per hour then by how much should she reduce her speed to be within the speed limit? [2 Marks]

Answer 1

Speed at which Anita is driving = 85.6 kmph.
Speed limit = 55 kmph.
∴ Anita should reduce her speed by:
85.6 kmph – 55 kmph. [ 1 Mark]

∴ Anita should reduce her speed by 30.6 kmph to be within the speed limit. [ 1 Mark]
