Hint: What was Cory's speed?

anonymous · Answer

the question doesn't say, it makes no sense

barrycarter · Answer

Well, if he rode 40 miles in 1.8 hours, his speed would be... ?

anonymous · Answer

that's problem I don't know what his speed would be.

barrycarter · Answer

OK, if he rode 40 miles in one hour, his speed would be... ?

anonymous · Answer

I'm lost I'm not good at word problems

barrycarter · Answer

OK. If you ride 40 miles in one hour, you are going at 40 miles per hour. Do you see why that is?

anonymous · Answer

Kinda, it makes some kind of sense

anonymous · Answer

Aw so the speed of something is the amount of miles it has gone right

barrycarter · Answer

The amount of miles it has gone divided by the time it took to get there. For example, 40 miles in 2 hours would be 20 miles per hour.

anonymous · Answer

Yea I get that but the problem is a decimal

barrycarter · Answer

Well, you can divide by a decimal... 40 divided by 1.8

anonymous · Answer

Aw ok so if I divide the decimal I'll get his speed

barrycarter · Answer

You'll get Cory's speed, correct.

anonymous · Answer

Now how would you write it in an inequality

barrycarter · Answer

If Lamar finished before Cory, was Lamar going faster or slower?

anonymous · Answer

He was going faster because the answer is 22.21

barrycarter · Answer

Right, so x > 22.2 is the final answer. Lamar is going faster than Cory, who was going 22.2 mph (to the nearest 1/10th)
