Answer 2

Answer:

A car travels a certain distance at the speed of 70 km/h in 6 hours, the speed of the car, if it wants to travel the same distance in 5hrs, is   $84km/h$

Step-by-step explanation:

• The speed (v) of a moving body is the change in its distance(d) with time(t)

                           $v=d/t$

From the question, it is given that

The car travels a distance with speed $v=70km/h$

time taken to cover this distance $t=6hrs$

so the distance traveled can be calculated as $d=vt=70*6=420km$

therefore speed of the car to cover the same distance in time $t=5hrs$

is

$v=420/5=84km/h$
