Question

Anita was driving at a speed of 85.6 km per hour. The road had a speed limit of 55 km per hour. By how much should she reduce her speed to be within the speed limit?

Answer 1

Speed at which Anita is driving = 85.6 km per hr. 

Speed limit = 55 km per hr.

∴ Anita should reduce her speed by 85.6 km per hr – 55 km per hr

= 30.6 km per hr. 

∴ Anita should reduce her speed by 30.6 km per hour to be within the speed limit.
