Question

A car traveled s kilometers in 6 hours with a speed of v kilometers per hour. Express the dependence of s on v. Using the formula, find:

s for v=65

The formula is ____

Answer 1

Answer:

$s=390\ km$

The formula is $s=6v$

Step-by-step explanation:

Let

s -----> the distance in kilometers

t ----> the time in hours

v ----> the speed in km/h

we know that

The speed is the ratio of the distance by the time

$v=\frac{s}{t}$

Solve for s

$s=vt$

we have

$t=6\ h$

therefore

The formula is $s=6v$

For $v=65\ km/h$

substitute in the formula

$s=6(65)$

$s=390\ km$
