Answer 1

$\huge {\underline {\underline {\mathbb {\red {Answer:-}}}}}$

1. speed = 20km/hr

time = 2hr

distance = speed × time = 20×2 = 40 km

_____________________________________

2.

in the first case :

time = 3hrs

speed = 40km/hr

distance = speed × time = 40 × 3 = 120km

In the second case :

distance = 120 km

time = 4hrs

Speed = distance/ time = 120/4 = 30km/hr

_______________________________________

3.let the distance be x km

when speed = 2km/hr

so

when speed = 6km/hr

distance = x+4 km

take taken is same in both cases so

x/2 = (x+4)/6

6x=2x+8

4x=8

x= 2

so the actual distance is 2 km
