Question

I travelled at 60km/hour and took 2hours for a certain journey.How long would it have taken me if I had travelled at 50km/hour?​

Answer 1

if you would travel 50km/h then the time will be 2.4hours

Explanation:

speed=v1=60km/h

time=t1=2h

speed=v2=50km/h

time=t2=?

as we know that

v1×t1=v2×t2

evaluating the expression

(v1×t1)/v2=t2

putting values

`(60km/h*2h)/(50km/h)=t2`

`(120km/h^2)/(50km/h)=t2`

2.4hours=t2

i hope this will help you :)
