Answer:
1 hour and 23 minutes
Step-by-step explanation:
11:32-10:09=1:23
Thinking through this logically, one hour after 10:09 is 11:09 and we know that it took him longer than this.
We can then subtract the minutes without having to worry about the base-60.
32 minutes -9 minutes =23 minutes
We then add the 23 minutes to the 1 hour and determine that it took him 1:23 (one hour and twenty-three minutes).
Use proportions:
height/shadow
2.6/1.24 = x/38.25
Cross multiply
1.24x=99.45
x = 80.2016129
