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.

<h2>
<u>every month the amount of money increases by a factor of 1.01</u></h2>
Explanation:
when t is 0 M(t) is 1000
when t is 1 M(t) is 1000 times 1.01
when t is 2 M(t) is 1000 times 1.01 squared which also looks like this:
1000* 1.01* 1.01
so in the end the factor is 1.01 because that is what is getting added each month (each month another 1.01 appears)
