Question

A woman jogging at 6 mi/h passes a man biking in the opposite direction at 12 mi/h. If they maintain their speeds, how far from each other will they be 10 minutes after passing? a. 1/2 mi b. 8mi c. 6mi d. 3mi

Answer 1

Since the woman is jogging at 6 mi/h, in 10 minutes she will have jogged:

`(10)/(60)\cdot6=(60)/(60)=1mi`

in a similar way, we can find the distance that the man traveled in 10 minutes, considering his speed of 12 mi/h:

`(10)/(60)\cdot12=(120)/(60)=2mi`

since the woman traveled 1 mile and the man traveled 2 miles, we have that after 10 minutes, they are 1+2= 3 miles apart
