Answer 1

Answer: 15.867 min

Explanation:

Given

Ben took
`1\ h\ \text{and}\ 23\ min\ 12\ s` to complete 15 km

While Mike take
`1\ hr\ 39\ min\ 4\ s` to complete the same

converting time into miniutes

Ben time

`\Rightarrow 60+23+(12)/(60)=83.2\ min`

Mike time

`\Rightarrow 60+39+(4)/(60)=99.0667\ min`

So, mike waited for

`\Rightarrow 99.067-83.2=15.867\ min`
