1/6 hours
Step-by-step explanation:
It takes leo 15 minutes = 15/60 = 0.25 hours to circle to school with speed of
12km/hr .
Distance covered = speed*Time.
Distance covered = 12*0.25
Distance covered= 3 km
So the distance to be covered each time is 3km.
If speed increase to 18 km/he
Time taken = distance/speed
Time taken = 3/18
Time= 1/6 hour
Or 1/6 * 60 = 60/6 = 10 minutes

is the same as
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.
