Question

1. 100 kilometers at 20 km/h?

Answer 1

Answer:

1. 5 hours

2. 4 hours

Reason:

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

Answer 2

$\\ \rm\hookrightarrow Speed=\dfrac{Distance}{Time}$

$\\ \rm\hookrightarrow Time=\dfrac{Distance}{Speed}$

So

#1

$\\ \rm\hookrightarrow Time=\dfrac{100}{20}=5h$

#2

$\\ \rm\hookrightarrow Time=\dfrac{180}{45}=4h$
