Question

A person is walking with the speed of1 1/8 km per hour.How much time does require to reach a goal at the distance of 5 1/16km?

Answer 1

Step-by-step explanation:

$Speed \: of \: the \: person = 1 \frac{1}{8} \: Km/hr \: \\ = \frac{9}{8} \: Km/hr \: \\ Distance = 5 \frac{1}{16} Km \\ = \frac{81}{16} Km. \\ time \: = \frac{distance}{speed} \\ = \frac{ \frac{81}{16} }{ \frac{9}{8} } \\ = \frac{81}{16} \times \frac{8}{9} \\ = \frac{9}{2} hr =\frac{9}{2}\times 60 \:min\\=9\times 30\\=270 minutes \\=4\: hr\:30\:minutes$

Answer 2

It will take 4.5 hours to cover distance of 5 1/16km

Step-by-step explanation:

Speed of person =$1\frac{1}{8} km/hr=\frac{9}{8} km/hr$

Distance traveled = $5\frac{1}{16} =\frac{81}{16} km$

Time taken to cover distance of $\frac{81}{16} km = \frac{Distance}{Speed}$

Time taken to cover distance of $\frac{81}{16} = \frac{\frac{81}{16}}{\frac{9}{8}}$

Time taken to cover distance of $\frac{81}{16} =4.5 hours$

Hence it will take 4.5 hours to cover distance of 5 1/16km
