Answer:
3hr 31mins
Step-by-step explanation:
First we convert miles to kilometers
1 miles to km = 1.60934 km
26.2 miles = 26.2 x 1.60934 = 42.164708
A typical marathon approx = 42.165km
If our runner covers 12 km = 1 hr
then he'll cover 42.165km = 42.165/12 = 3.5137 hrs
= 3 hrs + (0.514 * 60 mins) = 3hrs + (30.84mins)
Allan going at that speed would complete the marathon in appox = 3hrs : 31mins.
