Matt drove to the lake and back . the trip there took three hours and the trip back took fours hours . what was matt’s average speed on the trip there if he averaged 45 km/h on the return trip ?

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  =

                                                         =

                                                         = 60 km/hr

Thus Matt’s average speed on the trip there was 60 km/hr

his chances of getting a coin of higher value is 4/19
