A train covers 165 km in 1.5 hours. Find the constant variation.

110

Step-by-step explanation:

To find the constant of variation, divide the number of km by the number of hours:

165/1.5

= 110

This means that the speed of the train is 110 km per hour.

So, the constant of variation is 110.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
