Question

a bus travels a distance of 75 kn in 3 hours at uniform speed express its speed in km/ hour and m/ s​

Answer 1

Answer:

Given:

Distance = 75km

              = 75*1000m

              = 75000m

Time taken = 3hrs

                   = 3*3600s

                   = 10800s

Explanation:

Speed in km/hr:

Speed(v) = $\frac{distance}{time}$

v = $\frac{75km}{3hr}$

v = 25km/hr

Speed in m/s:

v = $\frac{distance}{time}$

v = $\frac{75000m}{10800s}$

v = 6.9m/s
