Answer:

1. 60 km/h

2. 455 km/h

3. 82.5 km/h

4. 23 km/h

5. 60 km/h

6. 5 h

7. 4 h

8. 5.5 h

9. a. 25 km/h

b. 0.416.66 km/m

Step-by-step explanation:

1-5 use the formula of d= st

example:

2 hours at 30 km/h

D= st

D= (30)(2)

D= 60 km/h

1-6 use this:

Speed = ?

Distance = ?

Speed =distance/time

Time=distance/speed

Both units of speed and distance are same so,no change in units.

example:

250 kilometers at 50 km/h

D= 250÷50= 5 h
