Question

Mr Daruwala takes 10 hours to cover a
distance of 600km. If his average speed for
the first 240km is 80 kmph, then find his
average speed for the remaining part of the
journey​

Answer 1

Step-by-step explanation:

600km in 10hrs

d=240km

t=?

s=80hrs

t=240/80=3hrs

240km in 3hrs

then

600-240=360km

10-3=7hrs

avg speed=360/7

s=51.4kmph

hope this helps you.
