Swiss Alps Activity Speed Pretest

A submarine travels 600 meters in 2 hours, what is the speed of the submarine? Once speed is solved, convert the speed to cm per hour (Velocity=Distance/Time).

• 30,000 cm/hr

• 120,000 cm/hr

• 300 m/hr

• 3,000 cm/hr

Answer explanation

The speed of the submarine is calculated as 600 meters / 2 hours = 300 m/hr. To convert to cm/hr, multiply by 100 (since 1 m = 100 cm), resulting in 30,000 cm/hr. Thus, the correct answer is 30,000 cm/hr.

If Johnny Football runs 40 yards in 6.3 seconds, how fast is he moving? Round your answer to the nearest hundredth.

• 25.2 yd/s

• 15.44 yd/s

• 6.35 yd/s

• 7.45 yd/s

Answer explanation

To find Johnny's speed, divide the distance by time: 40 yards / 6.3 seconds = 6.349 yd/s. Rounding to the nearest hundredth gives 6.35 yd/s, which matches the correct answer.

If I live 3 miles from school and leave my house at 8:20am, how fast will I need to drive to be there by 8:30am?

• 30 mph

• 18 mph

• 100 mph

• 22 mph

Answer explanation

To reach school by 8:30am, you have 10 minutes (or 1/6 hour) to cover 3 miles. Speed = distance/time = 3 miles / (1/6 hour) = 3 * 6 = 18 mph. Thus, you need to drive at 18 mph.

If Justin Bieber is driving his car 55 miles per hour for 5 hours, how far will he have traveled?

(distance = velocity x time)

• 220 miles

• 275 miles

• 150 miles

• 300 miles

Answer explanation

To find the distance, use the formula: distance = velocity x time. Here, distance = 55 miles/hour x 5 hours = 275 miles. Therefore, the correct answer is 275 miles.

SpongeBob swims 10 miles per hour and gets to a town 75 miles away. How long did it take him?
(time=distance/velocity)

• 10 hours

• 7.5 hours

• 5 hours

• 15 hours

Answer explanation

To find the time, use the formula time = distance / velocity. Here, time = 75 miles / 10 miles per hour = 7.5 hours. Thus, the correct answer is 7.5 hours.

On the graph below, graph the following points and label them. A (1,7) B (9,5) C (3,0)

If the Y Axis is Distance and the X Axis is Time, which vehicle is moving faster, A or B?

• A

• B

Answer explanation

To determine which vehicle is moving faster, compare the slopes of their lines on the graph. A steeper slope indicates a higher speed. Since vehicle A has a steeper slope than vehicle B, vehicle A is moving faster.
