Answer:
Given:
Time = 50 minutes
=》 50/60 hr
Speed = 45 km/hr
Distance = Speed × Time
=》 45 × 50 / 60
=》 37.5 km
Now,
In the second case:
Distance = 37.5 km
Speed = 30 km/hr
Time = Distance / Speed
=》 37.5 / 30
We can directly convert the time in minutes from hours by multiplying by 60. We will do this 5o simplify our calculation.
=》 37.5 × 60 / 30
=》 75 minutes.

Answer:
Step-by-step explanation:
v=45km/h
s=?
t=50min
v=30km/h
s=vt
convert km/h to m/s
30km/hr/18/5
18*6=108
s=vt
replace values
108*50
5400meters
