Question

Caroline drove 350 miles to her grandmothers house trip took her 5 1/4 hours what was your average speed in miles per hour

Answer 1

You have {{{R=unknown}}}, something for which to solve;

{{{T=5&1/4}}} hours;

{{{D=350}}} miles.

Keep your calculations in miles per hour.

{{{R=D/T}}}

{{{R=350/(5&1/4)}}} miles per hour

You have no reason to convert anything into minutes. Your given values are in miles and in hours, and a very common unit for travel rates is MILES per HOUR.

Answer 2

On the day that Caroline made her road trip, I didn't
leave the house, so my average speed was zero.
