Question

Two mem start together to walk a certain distance once at 3.75 kmph and other at 3 kmph the former arrives half an hour before the latter find the distance

Answer 1

Answer:

Let the Answer be: x

∴ Ans: $\sqrt[1]{x}$ = x

Answer 2

Answer:

Step-by-step explanation:

     

A (3.75km/h)......................................................

B (3km/h)

let B takes x hrs to arrive

so, A takes x- 1/2  hrs

let the distance is y km

distance = speed × time

y = 3.75(x-1/2)

y = 3.75x - 1.875

y = 3x

therefore,

3x = 3.75x - 1.875

0.75x = 1.875

x = 1.875/0.75

x = 1875/750

x = 2.5 hrs

y = 3x = 3×2.5 = 7.5 km

distance = 7.5 km
