⇒ 1.5 =?
· 1 +
⇒ 1.5 =?
+
⇒ 1.5 =?
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =?

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.
