distance = speed * time
170 miles = 68 * time
(divide both sides by 68)
170 / 68 = time = 2.5 hours

... *sigh*... okay, so you take 68 and multiply it by 2. What do you get? 136! Okay, now... 170 minus 136 is 34. If you use your head, you'll realize that 34 is half of 68 miles/hour, so that would be 2 and a half hours total.
68 = 1 hour
68 = 1 hour
+34 = 1/2 hour
---------------------
170 = 2 1/2 hours
Easier method: punch in 170 in a calculator, and divide it by 68!

170 divided by 68. You'll get the time in hours.

Sweetie, I won't give you the answer since it is your homework, but I will let you in on a secret.
The answer is in the division. How many times does 68 divide into 170? Anyone giving you a direct answer is teaching you to cheat!!!!

Two hours and thirty minutes, not mostly a long drive. Division is the way to go.

Roughly two and a half hours if you have a full tank of gas. Stopping to pee or fill up will add another half hour to your trip.
