Interpreting Time and Distance Functions

In this graph, a bus is:

• moving

• standing still (stationary)

• speeding up (accelerating)

• slowing down (decelerating)

The speed of a bus in this graph is:

• fast

• slow

• zero

• the speed of light

In this graph, the bus is:

• moving steadily

• not moving

• slowing down (decelerating)

• speeding up (accelerating)

In this scenario,

• the bus drove fast through the streets for 20s, and then it started to return back to the depo.

• the bus had a steady speed for 80s.

• the bus drove fast through the streets for 20s, but then it lowered the speed around the main square.

• the bus drove 400m total.

This line is:

• curved

• vertical

• horizontal

• none of these

A person drives their speed boat 22 km at 45 km/hr how, how long will it take them to go the 22 km?

• 48 hrs 
• 0.48 hrs
• 990 hrs
• 45 min

If a robot chases you down at a speed of 900 m/s for a distance of 200 m. How long has the robot been chasing you?

• 0.22 s
• 4.5 s
• 180000 s

Joanna drives for 400km at an average speed of 80km/h. How long was her journey?

• Joanna's journey was 5hrs long
• Joanna's journey was 10hrs long
• Joanna's journey was 20hrs long
• Joanna's journey was 15hrs long

How far will a person go if they jog for 2 hours at a speed of 12 km/hr?

• 6 km
• 0.5 km
• 10 km
• 24 km

What equation do you use to calculate speed?

• s = d/t

• t = d/s

• d=ts
