Question

A car travels 40km at a uniform speed of
40 km/h. What should be its speed for
the next 80km if the average speed for
the entire journey is 60 km/h.​

Answer 1

Answer:

pal its 80km/h

Explanation:

average speed = total distance by total time taken

60=(80+40)/t

t=2hrs

time taken to travel 40km for 40km/hr

is t=40/40=1hr

so time taken to cover 80km is 1hr so

speed=dist/time=80/1=80km/hr
