Answer:
36 minutes
Step-by-step explanation:
time = distance / speed
time = (7.2×10² km)/((1.2×10³ km)/(60 min)) = (7.2×60/1.2)×10²⁻³ min
= 360×10⁻¹ min
= 36 min
It takes sound about 36 minutes to travel 720 km.
Answer:
Step-by-step explanation:
As 360°= 2 π Radian
1 Radian =
1. Sin(-1)= Sin ( )
= Sin (-57°16'22")=-0.84147
2.
= (229°54'32")
=75.963757 Degrees
3.
= (5°43'38")
= 84.26083 Degrees
