Question

Parker ran on a

treadmill at a constant speed for the length of
time shown. How many miles did Parker run?
Explain.

Answer 1

d = 2.76 miles

Explanation:

It is given that,

Speed of Parker, v = 6 mph

Time taken, t = 27 minutes 39 seconds = 27.65 minutes = 0.46 hour

Let d is the distance covered by Parker during his motion. We know that the distance covered by an object is equal to the product of speed and time taken. It can be given by :

`d=v* t`

`d=6\ mph* 0.46\ h`

d = 2.76 miles

So, the Parker will run 2.76 miles. Hence, this is the required solution.

Answer 2

2.765 miles

Explanation:

Speed = 6 mph = 6 mile per hour

Time = 27:39, which means 27 minutes and 39 seconds.

So in order to find the distance Parker ran, first we need to convert this time to hours.

There are 60 minutes in 1 hour and 60 seconds in 1 minute. So to convert minutes to hour, we divide the by 60. To convert seconds to hour we divided them by 60 twice, once for converting them to minutes and then to second.

So,

27 minutes and 39 seconds =
`(27)/(60)+(39)/(60 * 60) = (553)/(1200)` hours

Since, Distance is defined as:

Distance = Speed x Time

The distance hat Parker ran would be:

Distance =
`6 * (533)/(1200)=2.765` miles

This means Parker run for 2.765 miles
