Question

A long distance covered by Rakesh in 6 hrs. He covers 1/2 of it at 4kmph and other half at 2kmph. The total distance is​

Answer 1

Answer:

84 km

Step-by-step explanation:

because :

formula of speed,time and distance

s = d/t

t = s × d

d = s × t

distance covered at the speed y in 6hrs : x

distance covered at the speed 4 in 6hs : x/2

or 4 × 6

= 24km

distance covered at the speed 2 in 6hs : x/4

or 2 × 6

= 12km

find the value x or distance covered at first :

4 × 6 = x/2 or 24 = x/2

x = 24 × 2

x = 48km

so, 48 + 24 + 12 = 84

So, in total Rakesh covered 84kms
