Answer 1

Answer:

80km

Step-by-step explanation:

x/40+x/8=6

=> 6x/40=6

=> x=40km

So, total distance = 2x

= 80km

Answer 2

Answer:

40 km

Step-by-step explanation:

let say diatance is x

so time taken for distance x is distance/time,

therefore x/40+x/8= 6hr

simplyfy it by taking lcm of 40 and 8, which is 40

1x/40+5x/40=6,

6x = 6*40

x = 40
