A truck driver travels 55 km in 1 hour. He then drives a speed of 35km/hr for 2 hrs. Next, he drives 175 km in 3 hrs. What was his average speed?
Should i add up the total distance and total time taken then solve?
Yes.
(55 + 70 + 175)/(1 + 2 + 3) = 50 km/h
35+35 is 70 bc he’s traveling at 35km/h for 2 hours
50 KM/H
In 2 hour 35km/h
so 2 × 35 = 70
the rule of average speed is total distance ÷ total time
We will put 55 + 70 + 175 ÷ 1 + 2 + 3 = 50
So the answer is 50km/h
Yes, to find the average speed, you need to divide the total distance traveled by the total time taken. In this case, the truck driver traveled a total distance of 55 km + 35 km * 2 + 175 km = 300 km in a total time of 1 hour + 2 hours + 3 hours = 6 hours.
To calculate the average speed, divide the total distance (300 km) by the total time (6 hours):
Average speed = Total distance / Total time
= 300 km / 6 hours
= 50 km/hr
Therefore, the average speed of the truck driver for the entire trip was 50 km/hr.
