1. A hiker covers a distance of 1500 m in 20 minutes. What is the average speed of the hiker? m/s
2. How many seconds would it take a lorry travelling at a constant speed of 20 m/s to cover a distance of 30 km? s
3. How many metres does a cyclist travel in 5 minutes when cycling at a steady speed of 6 m/s? m
4. A car has an average speed of 30 m/s for a motorway journey of 51 km. A speed of 1 m/s corresponds to a speed of 2.2 miles per hour.
(i). What is the average speed of the car in miles per hour? mi/h
(ii). How many seconds did it take the car to complete its journey? s
(iii). Did the car exceed the speed limit of 70 miles per hour at any time during its journey?
Yes.
No.
Perhaps.
5. A car is travelling at a speed of 30 m/s. The driver then applies the brakes so that the car decelerates steadily for 3 s until the speed of the car reaches 15 m/s. Calculate the deceleration of the car. m/s2
6. A cyclist is cycling at a constant speed of 3 m/s . The cyclist then accelerates uniformly at 0.8 m/s2 for 10 s. What speed is reached by the cyclist in this time. m/s
