1. paulo ran a marathon in about 1.56 x 10^4 s.
(a) write paulo’s time in standard notation.
(b) miguel ran a marathon in 4 h and 16 min. who ran the race in the shorter amount of time? show your work.

A) 1.56 x 10^4 = 15,600 sec

B)  Paulo =  15600s / 60minutes = 260 mins/1 hour = 4h 10 mins

so Miguel = 4h 16min

and Paulo ran the race in the shorter amount of time, about 6 minutes faster than Miguel did.

Hi, I really hope this helps! Hope I wasn't to late XD
