Question 211903
Emile wants to win the 100 yard dash at the track meet. If he runs 4.9 miles per hour, how many minutes will it take him to run the race?


100 yards = {{{100/1760}}} miles -----> 1,760 yards = 1 mile


D = ST, or T = {{{D/S}}}

Since we're looking for time, in minutes, then we will 1st calculate the time in hours, as follows:

{{{T = (100/1760)/4.9 = (100/1760)*(1/4.9)}}} = 0.011595547 hours. Converted to minutes, 0.011595547 becomes 0.695732839, or approximately {{{highlight_green(0.7)}}} minutes.
