5--------------25

20------------100

Explanation:

Given the table show value of time and distance.

Time-------Distance

1--------------?

2-------------?

5------------25

?------------100

We know that formula for speed is given by

`Speed = (distance)/(time)`

Here, The missing values are in 1sr, 2nd and 4th rows

For 3rd Row:

Distance=25m

Time=5min

Speed is given by

`Speed = (distance)/(time)`

`Speed = (25)/(5)`

Speed = 5m/min

Using Value of speed,

We can find missing values

For 1st Row:

Speed: 5m/min

Distance=?

Time=1min

Speed is given by

`Speed = (distance)/(time)`

`5 = (distance)/(1)`

Distance=5x1=5

A distance of 1st row is 5m

For 2nd Row:

Speed: 5m/min

Distance=?

Time=2min

Speed is given by

`Speed = (distance)/(time)`

`5 = (distance)/(2)`

Distance=5x2=10

A distance of 1st row is 10m

For 4th Row:

Speed: 5m/min

Distance=100m

Time=?

Speed is given by

`Speed = (distance)/(time)`

`5 = (100)/(time)`

time=100/5=20

A time for 4th row is 20min
