Question

Andy took a bus and then walked from his home to downtown.
For the first 1.6 hour, the bus drove at an average speed of 15
km/h. For the next 0.4 hours, he walked at an average speed
of 4.5 km/h. What was the average speed for the whole
journey?

Answer 1

Answer:

12.9

Explanation:

1.6x15=24

0.4x4.5=1.8

24+1.8=25.8

1.6+0.4=2

25.8/2=12.9
