I've done this question before
Answer:
90 meters
Explanation:
To find the distance in which Bob catches up with Wendy, you first write down the motion equations of both Bob and Wendy.
Wendy has a constant speed, then you have:
(1)
Bob has an accelerated motion, then, his equation of motion is:
(2)
v1: constant speed of Wendy = 3.00 m/s
v2: initial speed of Bob = 0 m/s
a: acceleration of Bob = 0.200m/s^2
When Bob catches up with Wendy x1 = x2, then you equal both equations and solve for time t:
you replace the values of a and v1:
Finally, you replace this value of time either the equation for x1 or the equation for x2, and you calculate the distance:
hence, Bob catches up with Wendy for a distance of 90m

Dear Friend,
I received your letter a few days back. And because I was busy with work, I couldn't write a reply to you immediately. However, here is my well-detailed reply to your request. I hope you find it satisfactory. I am excited to learn that you wish to go on a tour to Nepal. For the advice, here is my suggestion for some places for you to visit.
1. Kathmandu: this is the capital of Nepal. It also doubles as the capital city. The atmosphere there is electric. The streets are wide and there are old monumental buildings there.
2. Bhaktapur: here you find interesting things around. It is the third-largest royal city. Durbar square is a nice place to visit.
3. Pokhara: this place has the largest population and the city is cleaner compared to most other big cities around. It has wonderful places to relax. And if you enjoy hiking this is the place for you.
4. Chitwan National Park: I know you love watching wildlife. So this is a must for you to visit. You get to see amazing animals such as rhinos, Bengal tigers, leopards, etc.
However, due to space and for me not to bore you, here are other honorable mentions
Trekking in the Langtang region, Swayambhunath, known as Monkey Temple. You should also consider the Everest & the Trek to Base Camp.
I hope you will enjoy your stay to the fullest. Don't forget to send me details of your tour after your visit.
I love you, friend.
Yours sincerely,
MyName
