Using the concept of proportional relationship, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.

Using the concept of proportional relationship :

For Evian :

1.5 miles = 15 minutes

1 mile = x

1.5x = 15

x = 15 / 1.5

x = 10 minutes

For Toby :

2/3 miles = 6 minutes

1 mile = x

2/3x = 6

x = 6 ÷ 2/3

x = 9 minutes

For J :

0.75 miles = 9 minutes

1 mile = x

0.75x = 9

x = 9 / 0.75

x = 12 minutes

Therefore, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.
