Question

1 The car on the motorway can travel 1860 metres in 60 seconds.

a Write down the formula for speed.

b Work out how fast the car is going. Don’t forget the units!

2 The dog runs 1980 metres in 5 minutes. How fast is he running? (Remember, there are 60 seconds in each minute.)

3 Sometimes we know the speed of something, and we want to find out how far it will go in a certain time. The formula we need for this is:

Distance = speed  time


a How far will the girl cycle in 1 hour? (1 hour = 3600 seconds)

b How far will the train go in 60 seconds?

c How far will the cockroach run in 10 seconds?

4 How long will it take for the girl to cycle 4 km? The formula you need is:

Time = distance
speed

Answer 1

Answer:

1.

A: speed = distance/time

B: the car is going 31 meters per second

2.

the dog is going 396 meters per minute or around 7 meters per second (6.6)

i dont really know the context of the other questions after but if you can give it to me i might be able to answer them

I hope this helps (i answered 1 and 2 only)

Answer 2

1.
A. Speed=Distance/Time
B. The car is going 32.66 m/s

2. Using Speed=Distance/Time, the speed of the dog is 396 m/m

3. Time=Distance/Speed

Distance = Speed * Time

A. We need to know the speed to use the equation Distance=Speed*Time.

B. Same thing as above.

C. The same as well.

4 The same as above.

Time=Distance/Speed
