1. s = 2 m/s

2. d = 130 m

3. t = 7 s

4. d = 56 mi

5.  t = 0.15625 h

6. s = 72 mph

Solution

For motion at a constant speed, the formula can be used:

d = v x t or d = s x t

v = velocity

s = speed

1. s = d : t = 40 m : 20 s⇒ s = 2 m/s

2. d = s x t = 13 m/s x 10 s ⇒ d = 130 m

3. t = d : s = 63 m : 9 m/s ⇒ t = 7 s

4.  d = s x t = 28 mph x 2 h ⇒ d = 56 mi

5. t = d : s = 24 mi :  153.6 mph ⇒ t = 0.15625 h

6. s = d : t =1296 mi : 18 h⇒ s = 72 mph
