How long did it take that person to drive the first 500 miles?

anonymous · Answer

10?

goldphenoix · Answer

Good. So keep 10 hours in mind.
So you drove 500 miles. Now you need 500 miles left.
Since he is driving 60 miles per hour, how long will it take him to drive 500 miles?

jdoe0001 · Answer

then you set 8.3 as a rational, 500/60, then simplify

jdoe0001 · Answer

500/50 simplifies already to 10

yeah

jdoe0001 · Answer

right and  $\bf \cfrac{500}{60} \implies \cfrac{25}{3} \implies 8 \cfrac{1}{3}$

jdoe0001 · Answer

$\bf \large 10+\frac{25}{3}  \implies \frac{55}{3} \implies 18\frac{1}{3}$
