Answer:
Step-by-step explanation:
40
h
Explanation:
We're asked to find the time it takes an object (bird) to travel
1800
km
at a constant speed of
45
km/h
.
We have our simplified speed equation:
speed
=
distance
time
Rearranging for time:
time
=
distance
speed
We're given:
speed
=
45
km/h
distance
=
1800
km
Plugging these in:
time
=
1800
km
45
km
