Q
- A person walking covers 5.20 m in 10.4 s. How fast is the person moving?
A

Q
- A man riding his 4 - wheeler at 60 km/hr. If he is riding it constantly at this rate for 1.5 hours, how far did he ride?
A
34. Given : s = 60 km/hr. t = 1.5 hours. Formula = speed equals d over t. D = st. Substitute = (60)(1.5) Solve = 90 km/hr Unit 6 concept 2 page 3
