Question

1. A truck travels a distance of 270 km in 5 hours. Calculate its speed in km/h and m/s.

Answer 1

Answer:

In km/h = 54 and in m/sec = 15

Step-by-step explanation:

Speed = distance /time

so. 270/5 = 54 in km/h

and in m/sec it it multiplied with 1000/3600

so. 54×1000/3600 = 15 m/sec

Answer 2

Question

A truck travels a distance of 270 km in 5 hours. Calculate its speed in km/h and m/s.

Solution:-

Distance travel by truck = 270 km

Time taken = 5 hours

Speed = ?

$\star\color{indigo}{ \bf \: speed \: = \frac{distance}{time} }$

$\color{black}{ \rm \: speed = \frac{270km}{5hrs} }$

Speed = 54 km/hr

Now we have converts in m/ s

$\rm \: 54 \: km \: hr {}^{ - 1} \times \frac{5}{18} \: m \: sec {}^{ - 1}$

we get

speed = 15 m/s
