Sarah types at a speed of 35 words per minute then hand writes 6 words per minute. She types for $t$ minutes and hand writes for $h$ minutes for a combined total of 240 words. Which equation represents this situation?
Answer:
A
Explanation
The correct answer is Choice A.
Construct an equation based on the two different writing speeds of Sarah.
Choice B is incorrect because the speeds and the minutes have been switched between typing and handwriting.
Choice C is incorrect because the speed should be multiplied with the corresponding time instead of being divided by the rates.
Choice D is incorrect because it includes the time it takes to write one word.
✨ Expert's Tip ✨
It would be a mistake to add the hourly rates together since the number of hours spent writing in hand and typing can be, and probably will be, different.
