What is the difference in average speed between two cars, one that traveled 160 kilometers in 5 hours, and the other that traveled 140 kilometers in the same time? Record and bubble your answer below.

The difference in average speed between two cars, one that traveled 160 kilometers in 5 hours, and the other that traveled 140 kilometers in the same time is:

2 km/h.

Step-by-step explanation:

a) Data and Calculations:

Let A = first car and B = second car

Distance traveled by first car = 160 kilometers (km)

Distance traveled by second car = 140 kilometers

Time taken by each car = 5 hours

Speed of A = 160/5 = 32 km/h

Speed of B = 150/5 = 30 km/h

Difference in speed =  2 km/h (32 - 30)

b) The average speed of a car is given by the distance traveled divided by the time taken to travel the distance.  The speed here is expressed in kilometers per hour (km/h).  It can also be expressed in meters per hour or second, etc.
