Answer:
[tex]distance = speed \times time[/tex]
speed » 90 km/hr
time » 10 mins.
But:
[tex]60 \: mins = 1 \: hour \\ 10 \: mins = ( \frac{10 \times 1}{60} )hours \\ \\ { \underline { \: time = \frac{1}{6} \: hours }}[/tex]
therefore:
[tex]distance = 90 \times \frac{1}{6} \\ \\ { \underline{ \underline{ \bf{ \: \: distance = 15 \: km \: \: }}}}[/tex]
