Question

A car completes a jurney in 3 hours 20 minutes
75 km per hour, if the speed is reduced into 50 km what time will he take to complete the journey​

Answer 1

Answer:- A car a complete journey in 3 min ok.= 3+20=23+75=98+50=148

= 148 speed Answer

Answer 2

Answer:

5 hours

Step-by-step explanation:

First velocity (v₁) = 75 km/hour

First time (t₁) = 3 hours 20 minutes = 3 ¹/₃ hours = ¹⁰/₃ hours

Question :

what time will he take to complete his journey at a speed of 50 km / hour?

Solution :

The mean of the question is to travel the same distance, but at different speeds. So, the first distance/space (s₁) = second space (s₂)

$\boxed{\bf s=v\times t}$

$\begin{aligned}\sf{s_1}&\sf{=s_2}\\\sf{v_1\times t_1}&\sf{=v_2\times t_2}\\\sf{75\times\dfrac{10}{3}}&\sf{=50\times t_2}\\\sf{250}&\sf{=50\times t_2}\\\sf{t_2}&\sf{=\dfrac{250}{50}}\\\sf{t_2}&\sf{=5}~\rm{hours}\end{aligned}$
