Question

Mr chain drive a distance of 420 kilometre at a speed of 60 km per hour in how much time does he complete the journey

Answer 1

Hi!

Here is your answer:

We know that,
$speed = \frac{distance}{time}$

$let \: the \: time \: = x \\ so \\ 60 = \frac{420}{x}$

60x = 420

$x = \frac{420}{60}$

$x = 8 hrs$
