Speed = Distance ÷ Time Kyle skateboards down the sidewalk in front of

the school, traveling at 24 km/h. How much time would it take him to travel 6.0 km?

Tamia and Jennifer are in a 3-legged race at Spring Fling. How far could they run if they ran 36 km/h for 5 min (convert to hours!)?

If you ran 15 km/h for 20 min, how much distance would you cover?

Maya doesn't want to be late for class so she rushes to Panera at lunch. How much time would it take Maya to walk 2 km to Panera for a salad if she walked at a rate of 4.5 km/h?

Kyle skateboards down the sidewalk in front of the school, traveling at 24 km/h. How much time would it take him to travel 6.0 km?

a) 24 km/h = 6.0 km b) x 24 km/h = 6.0 km n c) 24n = 6.0 n n d) 24n = 6.0 24 24

n = .25 hours (or 15 min)

Tamia and Jennifer are in a 3-legged race at Spring Fling. How far could they run if they ran 36 km/h for 5 min (convert to hours!)?

36 km/h = n ÷ .08 (5 min x 60)

36 x .08 = 3 km

If you ran 15 km/h for 20 min, how much distance would you cover?

15 km/h = n .3 hours (20 ÷ 60)15 x .3 = 4.5 km Maya doesn't want to be late for class so she

rushes to Panera at lunch. How much time would it take Maya to walk 2 km to Panera for a salad if she walked at a rate of 4.5 km/h?

4.5 km/h = 2 km ÷ n n = .4 h (2 ÷ 4.5)

Acceleration = Velocity 2-Velocity 1 Time

A roach moves down the hall at 1.2 m/s. When he sees the custodian coming down the hall, he begins to run. After 3.2 s, he is moving at 3.6 m/s. What is his acceleration?

.75 m/s² = 3.6-1.2 3.2 Instead of doing his work, Jake throws a textbook at Connor. After

just 0.2 s, it is moving at 10.4 m/s. Find its acceleration. 52 m/s² = 10.4 m/s – 0 m/s .2 s Luke and Zack decide to take the train to the Grand Canyon. The

train starts from rest and reaches a speed of 54 km/h in .2 hours. Find its acceleration.

270 m/s² = 54-0 .2 During his experiment, Eddie finds that his rocket starts from rest

and accelerates to a speed of 220 km/h in 22 s. What is the acceleration? 36666.7 m/s² = 220-0
