Question

what will be the speed of a body in m/s and km/h if it travels 40km in 5h​

Answer 1

Answer:

Distance (s) = 40km. = > Time (t) = 5hrs . = > 8 km /hr . 5 hrs = 5 × 60 × 60 sec.

Answer 2

Answer:

v = 8 km/h

v = 2.2222 m/s

Explanation:

d = 40 km/h

t = 5h

Find v = ? km/h

v = d/t

v = (40 km)/5h

v = 8 km/h

Find v = ? m/s

d = 40 km × 1000 m/1 km = 40000 m

t = 5 h × 3600 s/1 h = 18000 s

v = d/t

v = 40000 m/ 18000s

v = 2.2222 m/s Answer
