As we know that
average speed = total distance covered / total time taken
here, total speed is 30+25km/hr = 55 * 5/18 m/s
total time = 90 mins
so,average time = 15.27 / 90
=0.696

Here, the total distance covered = 120 km
total time taken= 3.5 hours
thus, the speed =120/3.5=34.29 km/hr
i.e. 9.53 m/s. Probably...
