HELPPPP BIG POINTSSSS THAT NEED HELP

Answer 1

4) 1 mi/6min * 60 min/1h = 1/10 mi/h = 0.1 mi/h

5) 175 mi *1 h/50 mi = 3.5 h

6) Mr. Smith - 9 min -from school to the park.

Mr. McNeil walks twice as fast, that means if s is a speed of Mr. Smith,

then 2s is a speed of Mr. McNeil.

Distance from school to the park = 9*s, distance from school to the park and back = 2*9*s.

Time= Distance/Speed

For Mr. McNeil:

Time from school to the park and back= distance from school to the park and back/ speed of Mr. McNeil = 2*9*s/2s = 9 min.
