Question

A bus trip takes 9 hours if the mean speed is 50 miles per hour. How many hours would this trip take if the mean speed was 45 miles per hour.

Answer 1

To calculate the new trip duration, the total distance of 450 miles is divided by the new mean speed of 45 mph, resulting in a 10 hour travel time.

Step-by-step explanation:

The question asks how long a bus trip would take at a different average speed. To solve this, first calculate the total distance of the trip using the original speed and travel time. If the bus travels for 9 hours at 50 miles per hour, the distance can be calculated as:

Distance = Speed × Time = 50 mph × 9 hours = 450 miles.

Now, to find the time it takes to travel the same distance at a mean speed of 45 miles per hour, use the formula:

Time = Distance ⁄ Speed

Substituting the given values:

Time = 450 miles ⁄ 45 mph = 10 hours.

So, the trip would take 10 hours if the mean speed of the bus is 45 miles per hour.

Answer 2

Given

Bus takes 9 hrs

Mean speed : 50 miles per hour

To find

Mean speed 45 miles per hour.

hours?

steps-by-step explanation

divide 9 by 50 and then multiply by 45 .

then you will get the answer is 7.92

This trip. will take 7.92 hours at 45 miles per hour.
