Question: How would you annotate the math word problem below? Math Word Problem: To find the time it will take for a bicyclist to travel from Nogales to Tucson, use the expression d/s where d represents distance and s represents speed. Find the time if the bicyclist travels at a speed of 16 miles per hour.
(DO NOT SOLVE! JUST ANNOTATE(My teachers words not mine))

At noon a bicyclist is 50 miles from home, riding toward home at 10 miles per hour.

:

It's easier if you write the equation first:

D = 50 - 10x

:

(a) Make a table that shows the bicyclist�s distance D from home after 1, 2, 3, 4, and 5 hours.

Use the equation to make the table

x | d

1 | 40

2 | 30

3 | 20

4 | 10

5 | 0, he's home

;

(b) Write a formula that calculates the distance D from home after x hours.

we did

;

(c) Use your formula to determine D when ?? hours. Does your answer agree with the value shown in your table?

:

(d) For what times was the bicyclist at least 20 miles

from home?

x =< 3 hrs

Explanation:

its d! the final exam asked good luck
