Travel 70 miles, spent 2 hours on the first part of the trip and travel 30 miles, spent 1 hours on the second part of the trip ,then find the average speed?
35.33mph
34.00mph
33.33mph
30.33mph
Explanation:
Average speed=$\dfrac{Total distance}{Total time}$
Determine the total distance : 70+30=100
Determine the total time :2+1=3
Average speed=$\dfrac{100}{3}$.
Average speed=33.33mph
Average speed=$\dfrac{Total distance}{Total time}$
Determine the total distance : 70+30=100
Determine the total time :2+1=3
Average speed=$\dfrac{100}{3}$.
Average speed=33.33mph
