Question

3. Find the time in hours if
a) speed = 80 km/h and distance
= 20,000 m.​

Answer 1

Answer:

the hours is 25 hours ok bhai

Answer 2

$\color{red}\huge{\underline{\underline{\bf GIVEN\dag}}}$

• $\tt \purple{speed(v) = 80kmph =22.23{ms}^{ - 1} }$
• $\tt \purple{distance(s) = 20000m}$

$\color{red}\huge{\underline{\underline{\bf NEED\:TO\:FIND\dag}}}$

• $\tt \purple{time(t)}$

$\color{red}\huge{\underline{\underline{\bf SOLUTION\dag}}}$

$\tt we \: know \: that :$

$\boxed{ \tt \blue{ speed = \frac{distance}{time} }}$

$\implies \tt 22.23 = \frac{20000}{t}$

$\implies \tt t = \frac{20000}{22.23}$

$\orange{ \tt \therefore time(t) = 899.6 \: \: sec=0.24hr}$
