Total length of marathon = 26.2 miles
As we know, 1 mile = 1.61 km
Total length of marathon in km = 26.2 x 1.61 km = 42.182 km
As we know, 1 km = 1000 m
Total length of marathon in meters = 42.182 x 1000 m = 42182 m
Time Sally took to complete marathon = 3 hr 3 mins
or we can write = 180 min + 3 min = 183 min
In secs, we have = 183 x 60 s = 10980 secs
So, speed of Sally in m/sec = 42182 / 10980
Approx speed of Sally = 3.84 m/sec
As we know, 1 mile = 1.61 km
Total length of marathon in km = 26.2 x 1.61 km = 42.182 km
As we know, 1 km = 1000 m
Total length of marathon in meters = 42.182 x 1000 m = 42182 m
Time Sally took to complete marathon = 3 hr 3 mins
or we can write = 180 min + 3 min = 183 min
In secs, we have = 183 x 60 s = 10980 secs

Approx speed of Sally = 3.84 m/sec
