Answer:

1. 5 hours

2. 4 hours

Reason:

Formula for speed is speed = [tex]\frac{distance}{time}[/tex] , if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.

[tex]\\ \rm\hookrightarrow Speed=\dfrac{Distance}{Time}[/tex]

[tex]\\ \rm\hookrightarrow Time=\dfrac{Distance}{Speed}[/tex]

So

#1

[tex]\\ \rm\hookrightarrow Time=\dfrac{100}{20}=5h[/tex]

#2

[tex]\\ \rm\hookrightarrow Time=\dfrac{180}{45}=4h[/tex]
