Two friends talk on the phone to meet, both come out at the same time in their respective bicycles; one of them with a speed of 25 km/h and the other with a speed of 30 Km/h. If the distance that initially separates them is 120 km: 1. How far are they from each other's house? 2. How long after dating do they meet?

Attached photo. Please help! I need to know how to set it up.

2. A car is traveling at a speed of 31 m/s. a. What is its speed in kilometers per hour? b. Is it exceeding the 90 km/h speed limit?

Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 35 km/h and the other is moving at 40 km/h. In how many hours will they meet? A) 2.5 h B) 2.0 h C) 1.75 h D) 1.5 h F) 1.25 h

3. A tennis ball is thrown up in the air. It's height is given by h(t) = -5t2 + 23t + 2, where h(t) is in meters and t is in seconds. Use technology to answer: a.) What is the max height of the tennis ball? When does it occur? b.) How long was the tennis ball in the air?

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.

8) Two ships are 10 km apart and moving toward each other at 6.0 km/h and 4.0 km/h, respectively. A bird flies continuously back and forth between them at 20 km/h. What is the total distance traveled by the bird when the ships meet? I need to show all works physics flow chart

4. A plane traveling at 192 km/h [N] is blown eastward by the wind with a speed of 56.0 km/h. What is the velocity of the plane with respect to the ground? a. 1.36 x102 km/h [E 16.3o S]b. 2.00x102 km/h [N 16.3o E]c. 2.00x102 km/h [N 73.7o E]d. 2.48x102 km/h [E 73.7o S]e. 1.36 x102 km/h [N 73.7o E]

Two trains are 900.0 kilometers apart. One is in Portland. The other is in San Francisco. They both begin traveling toward each other at the same time. The Portland train travels with an average velocity of 80.0 km/hr South. The San Francisco train travels North with an average velocity of 65.0 km/hr North.a. At what time will the two trains meet?b. How far away will they be from Portland when they meet?
