a is the correct answer

please mark as brainliest

Answer 2

Answer:

Distance= 5km = 5000 m

Time= 20min = 0.333 hr = 20×60=1200 sec

a)In km/min

velocity(km/min)=5km/ 20min =0.25 km/min

b)In m/sec

velocity(m/s)= 5000m/1200s =4.1667 m/sec

c)In m/min

velocity(m/min)= 5000 m/ 20 min = 250m/min

d)In km/hr

velocity(km/hr)= 5km/0.333 hr =15 km/hr
