Jenna's sixth-grade class is taking a bus to the zoo. The zoo is 156 miles from the school. If the bus travels an average of 55 mi/h, about how long will it take to get to the zoo?

156 / 55 = ?

To calculate the time it will take to get to the zoo, we can use the formula: time = distance / speed. Let's plug in the given values:

Distance = 156 miles
Speed = 55 miles per hour

So the time it will take to get to the zoo can be calculated as:
Time = 156 miles / 55 miles per hour

To simplify the calculation, we divide 156 by 55:
Time ≈ 2.83636 hours

Since we need to provide an answer in terms of time, let's round the decimal to a reasonable value. In this case, we'll round to the nearest 15 minutes.

Time ≈ 2.8 hours

Converting this to minutes, we can multiply 0.8 hours by 60 minutes:
Time ≈ 2 hours and (0.8 * 60) minutes
Time ≈ 2 hours and 48 minutes

So, it will take approximately 2 hours and 48 minutes to get to the zoo.
