18 km/hr

220 km/hr

As the family travels then Their average speed for the entire trip is 55 km/hr They stop at a restaurant 90 km from home for lunch and then travel the final 20 km to the coast within 2 hours.

What is the average speed?

The maximum not unusual place formulation for common pace is the distance traveled divided via way of means of time taken. The different formulation, when you have the preliminary and very last pace, upload the 2 together, and divide via way of means of time taken.

So the average speed for the entire trip would be calculated by the formula that is :
Average speed = total distance traveled/ total time taken.
= 90+20/2= average speed.
= 55 km/hr.

Thus the average speed for the entire trip is 55 km/hr traveled by the family.
