Question

The distance of a train from a station, varies directly with the time, t. If d = 200 miles when t = 4 hours, find d when t = 6.

Answer 1

Any ideas? @balokkk

Answer 2

not at all

Answer 3

ohkk

Answer 4

\[\huge \bf d=k \times t\]
where d=distance , t=time and k=constant value.

If d=200 miles and t=4 hrs,
\[\huge \bf200=k \times 4\]
so,
\[\huge \bf k=\frac{200}{4}=50\]

Answer 5

If time=6 hrs and d=?
\[\huge \bf k=\frac{d}{t}\]
\[\huge \bf 50=\frac{d}{6}\]
solve for d .

Answer 6

can you solve it? @balokkk

Answer 7

d=300?

Answer 8

yeah. you are correct. @balokkk
