Velocity practice problems:

1. A spider travels across a driveway 3.6 m wide (south) with a speed of 14 cm/s. How long will it take to cross the driveway?

2. A hiker is at the bottom of a canyon facing the canyon wall closest to her. She is 280.5m from the wall, and the sound of her voice travels at 340.0m/s at that location. How long after she shouts will she hear her echo?

3. A motorist traveling on a straight stretch of open highway sets his cruise control at 90.0km/h (north). How far will he travel in 15 minutes?

4. A motorcycle travels 90.0km/h. How many seconds will the motorcycle take to cover 2.10 x 103m?

5. A cross-country rally car driver sets out on a 100.0km race. At the halfway marker (50.0km), her pit crew radios that she has averaged only 80.0km/h. How fast must she drive over the remaining distance to average 100.0km/h for the entire race?
