Answer 1

Answer:

$Speed = 159.4\ km/hr$

$Speed = 2.6\ km/m$

Step-by-step explanation:

The question has missing details; However, the given parameters are

$Speed = 99\ miles/hour$

Required

Determine the speed in

- kilometre per hour

- kilometre per minute

From the question; we have that

$1\ mile = 1.61\ kilometers$

$1\ hour = 60\ minutes$

$Speed = 99\ miles/hour$ can be rewritten as

$Speed = \frac{99\ miles}{hour}$

It can be further expressed as

$Speed = \frac{99\ *\ 1\ mile}{hour}$

Recall that $1\ mile = 1.61\ kilometers$'

So;

$Speed = \frac{99\ *\ 1.61\ kilometre}{hour}$

$Speed = \frac{159.39\ kilometres}{hour}$

$Speed = 159.39\ kilometres/hour$

$Speed = 159.4\ km/hr$ -- Approximated

Solving further to get kilometre per minute equivalent

$Speed = \frac{159.39\ kilometres}{hour}$

This can be rewritten as

$Speed = \frac{159.39\ kilometres}{1\ hour}$

Recall that $1\ hour = 60\ minutes$; So,

$Speed = \frac{159.39\ kilometres}{60\ minutes}$

$Speed = \frac{2.5565\ kilometres}{minute}$

$Speed = 2.5565\ kilometres/minute$

$Speed = 2.6\ km/m$ --- Approximated
