Answer:
1 day 4 hours and 20 minutes
Explanation:
Matthew burns 11 calories/min
How long it would take him to burn 18700 calories is given as shown below:
[tex]\begin{gathered} =\frac{18700}{11}\times\frac{cal}{\frac{cal}{min}} \\ =1700\times cal\times\frac{min}{cal} \\ =1700min \\ 60min=1h \\ 24h=1day \\ \text{Converting we have:} \\ =1700min\times\frac{1h}{60} \\ =28\frac{1}{3}h \\ =28h\text{ }20mins \\ \text{Converting to days, hours, minutes we have:} \\ =24h+4h+20min \\ =1day\text{ }4hours\text{ }20minutes \end{gathered}[/tex]Therefore, it would take him 1 day 4 hours and 20 minutes to burn those calories
