Answer:

90 km/hr

Step-by-step explanation:

let the total distance be x

tina took 7/3 hours to travel 4/9x distance at speed of 72 km/hr

so  

distance = speed x time

4/9x = 7/3×72

x= 378 km

now new time is 4 hrs + 12 mins

4 + 12/60 hours

time = 21/5 hours

speed = distance/time

=378×5/21

=90 km/hr
