Distance = 100 km

Speed = 20 km/h

Answer & Solution:

[tex] \sf \large t \: = \frac{distance}{speed} [/tex]

[tex] \sf \large t = \frac{100 \: km}{20 \: km /h}[/tex]

[tex] \sf \large t = \boxed {\sf{5 \: hours}}[/tex]

180 kilometers at 45 km/h

Given:

Distance = 180 km

Speed = 45 km/h

Answer & Solution:

[tex] \sf \large t = \frac{distance}{speed} [/tex]

[tex] \sf \large t = \frac{180 \: km}{45 \: km/h} [/tex]

[tex] \sf \large t = \boxed {\sf 4 \: hours}[/tex]

[tex] \mathbb{ \underline{ANSWER:}}[/tex]

  • [tex] \large \tt \: Speed = \frac{Distance}{Time} [/tex]

  • [tex] \large \tt \: Time = \frac{Distance}{Speed} [/tex]

#1.

[tex] \large \tt \: Time = \frac{100}{20} = \red{5 \: hours}[/tex]

#2.

[tex] \large \tt \: Time = \frac{180}{45} = \red{4 \: hours}[/tex]
