{Route2, Route3, Route4} (Total 3  outcomes)

Step-by-step explanation:

Given: There are 4 different routes from Ben's house back to their home in Garland.

Let Sample space for all outcomes: {Route1, Route2, Route3, Route4 }

Ben  chooses Route 1.

The possible outcomes of the routes taken by the family if Ben  chooses first:

{Route2, Route3, Route4}

Hence, the possible outcomes of the routes taken by the family if Ben  chooses first: {Route2, Route3, Route4} (Total 3 choices)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
