Question

A woman traveled 2445.9 miles in 18 hours five minutes what is the average speed of her flight in miles per hour

Answer 1

The average speed is 135.26 miles per hour

Solution:

Given that, woman traveled 2445.9 miles in 18 hours five minutes

To find: Average speed of her flight in miles per hour

Let us first convert 18 hours 5 minutes to hours

We know that,

$1 \text{ minute } = \frac{1}{60} \text{ hour }$

Therefore,

$5 \text{ minute } = \frac{5}{60} \text{ hour } = 0.083 \text{ hour }$

Thus we get,

18 hours five minutes = 18 hour + 0.083 hour = 18.083 hour

Given that, distance = 2445.9 miles

Average speed is given by formula:

$Average\ speed = \frac{distance}{time}\\\\Average\ speed = \frac{2445.9}{18.083}\\\\Average\ speed = 135.26$

Thus average speed is 135.26 miles per hour
