Exam-Style Question on Kinematics
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 406. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.
The distance from Wolverhampton to Cambridge is 115 miles.
Lynn drives from Wolverhampton to Cambridge leaving Wolverhampton at 10:30am. She assumes that her average speed will be 55 mph.
