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

Given:- Anita was driving at a speed
of 85.6 km/h,
speed limit is 55 km/h


Suchthat:- 85.6
- 55.0

= 35.6

therefore:- Anita needs to reduce the speed
of the car by 35.6 km/h

Answer 2

We will subtract 55 km/hour from 85.6 km / hour to achieve the answer of the reduction in speed needed.

Thus, reduction required in speed = Original speed - Speed Limit

85.6 - 55 = 30.6 km / hour
