Question

Determine the time taken when distance=27km,speed=45km/hr

Answer 1

Time taken $36\ min$ for distance$=27\ km$,speed$=45\ \frac{km}{hr}$

Step-by-step explanation:

Given,

Determine the time taken when distance$=27\ km$,speed$=45\ \frac{km}{hr}$

• If Speed is in Kilometer per hour (Km/h), distance must be in Kilometer.

• If Speed is in meter per second(m/s), distance must be in meter.

We know,

$Distance(s)=Speed(v)\times time(t)$

⇒$time(t)=\frac{Distance(s)}{speed(v)}$

Plug the value in above equation,

⇒$time(t)=\frac{27}{45}$

∴ $time(t)=0.6\ hr$

∵ $1\ hr$ is equal to $60\ min$

Then $0.6\ hr$ is equal to $36\ min$

So, Time taken $36\ min$
