Answer:
a,e,d
Explanation:
i got it right when i was doing study island
Solution :
We know that :
Formula for Gravitational force is given by :

where, G is the gravitational constant
M is the mass of the bigger body
m is the mass of the smaller body
r is the distance between the two bodies.
And the formula for the centripetal force is given by :

where, m is the mass of the rotating body
v is the velocity
r is the radius of rotation of the body.
We know that mathematically, the gravitational force is equal to the centripetal force of the body.
Therefore,



Hence derived.
Part a
The average speed = total distance traveled upon total time taken.
we know, distance =speed × time
Average speed = 
insert the values:


=
km/hr
= 46.43 km/hr
Hence, the average speed for the trip is 46.43 km/hr.
Part b
the total distance between two cities via this route would be the average speed times the total time taken = 46.43 km/hr × 2.9 hr = 134.65 km
(because 175 minutes = 2.9 hours)
Hence, the total distance between two cities via this route is 134.65 km.
