Answer 1

Answer:

Janta express runs at a speed = 153 km per hour

= \dfrac{153\times \1000\ }{3600}

3600

153×\1000

m per sec

Since, 1 km = 1000 m

= \dfrac{153\times \10\ }{36}

36

153×\10

m per sec

= \dfrac{153\times \1000\ }{36}

36

153×\1000

cm per sec

Since, 1 m = 100 m

= 4250 cm per sec

Hence, the speed is 4250 cm per sec.
