Answer:
Matt’s average speed on the trip there was 60 km/hr
Step-by-step explanation:
Given : . The trip there took three hours and the trip back took fours hours .
To Find: What was Matt’s average speed on the trip there if he averaged 45 km/h on the return trip ?
Solution :
On returning he took time = 4 hours
His speed on returning was 45 km/hr
So, the distance traveled = speed *time
= 45*4
= 180 km
Thus the distance of the trip is 180 km
On going He took time = 3 hours
Since he took 3 hours to travel 180 km
So his speed on going there was = [tex]\frac{Distance}{Time}[/tex]
= [tex]\frac{180}{3}[/tex]
= 60 km/hr
Thus Matt’s average speed on the trip there was 60 km/hr
