Solution :
a). It is given that Tyler swims 5 m in every 4 seconds. So we need to find the time taken to swim for 114 meters.
Thus,
5 m = 4 second
1 m = 4/5 second
1 m = 0.8 second
∴ 114 m = 114 x 0.8
= 91.2 seconds.
The equation to represent the proportional relationship is :

or

b).
quarts of white paint is required to to mix with the 4 quarts of the blue paint.
There are
quarts of white paint per quart of the blue paint because 5 divided by
is equal to
i.e.

The relationship is :


c). A factory manufactures 3 sparkling water bottles for every 8 plain water bottles.
8 plain water bottles = 3 sparkling water bottle
1 plain water bottle =
sparkling water bottle
= 0.375
∴ 600 plain water bottle = 0.375 x 600
= 225 sparkling water bottle
The proportional relationship is :
