Answer 2

☆To find:

• The speed

☆Given:

• Distance = 142km
• Time =2 hrs

☆Formula:

• $\sf \: speed = \frac{distance}{time}$

☆Solution:

Given data, distance = 142 km and time 2 hours

We know formula

$\longmapsto \: \sf \: speed = \frac{distance}{time}$

Putting values in formals we get,

$\longmapsto \: \sf \: speed = \frac{ \cancel{142}}{ \cancel2} \\ \\ \longmapsto \: \sf \: speed = 71$

$\qquad \qquad\sf \underbrace\green{ \boxed{ \frak{speed =71 \: km \: per \: /hours}}}$

Therefore the speed be 71 km per/hours
