Answer:
Step wise answer:
I think that question is wrongly written......
v should be 35km/h
then the increase in v = 9km/h
if v = 35km/min
than the increase in the v = 9km/min
First case
v = 35km/m
t = 5 hr = 300min
s = v × t
s = 35×300
s = 10500 km
second case
s = 10500km
v= 44km/min
t = s/v
t= 10500/44
t = 238.63 min
