Question

If a rickshaw travel at a speed of 30 kmph how far will it travel in three quarters of an hour.

Answer 1

1 hour = 60 min so three quarters is 45 min.so the rickshaw run km in 45 min = 45 by 60 * 30 show the rickshaw runs 22.5 km in 45 minutes that is three quarters.

Answer 2

Answer:

$In \: three \: quarters \:of\\ \: an \: hour \: the \: rickshaw\\ \: travels \: 22\frac{1}{2}\: km$

Step-by-step explanation:

/* We know that the time decreases then the distance travelled by a rickshaw decreases.*/

Therefore,

Time directly varies with the distance of a rickshaw.

$So, \:\frac{ x_{1}}{x_{2}}=\:\frac{ y_{1}}{y_{2}}\\</p><p>Here, \: x_{1}=30\:km , \: x_{2}=?\\y_{1}=1\:hour ,\:y_{2}=\frac{3}{4}\:hour$

$\:\frac{ 30}{x_{2}}=\:\frac{ 1}{\frac{3}{4}}$

$\implies 30\times \frac{3}{4}=x_{2}$

$\implies \frac{45}{2}=x_{2}$

$\implies x_{2}= 22\frac{1}{2}\: km$

Therefore,

$In \: three \: quarters \:of\\ \: an \: hour \: the \: rickshaw\\ \: travels \: 22\frac{1}{2}\: km$
