A runner was training for a race. She was able to run 16 miles in 96 minutes. To the nearest hundredth, what is her average speed?

Answer 1

#color(green)(10.00 " miles per hour")#

#(cancel(16) " miles")/(cancel(96)_cancel(6)cancel(" minutes"))xx(cancel(60)^10 cancel("minutes"))/(1" hour") = 10" miles"/"hour"#

Expressing this "to the nearest hundredth seems silly (since the result is an exact integer); perhaps the result was intended to be in miles/ minute, in which case: #color(white)("XXX")(16" miles")/(96" minutes")=1.66bar6 "miles"/"minute"# which rounded to the nearest hundredth would be #1.67 "miles"/"minute"#
