The summer camps had a field trip from the campus to fragrance hill. they traveled at an average speed of 65 km/h in the first 2 hours. after that, traveled at another average speed of 78 km/h. if the distance between the campus and fragrance hill is 364 km, what was the total time for the field trip?

sup bro, im dumb, but this is what i found xd
