Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed

swat32

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

$h=\frac{1.150}{60} \\h=2.5$

Now we determine the distance Michael traversed during those 2.5 hours:

$d_{1} =2.5.75 \\d_{1} =187.5\\$

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

$d_{2} =2.81 \\d_{2} =162$

He also traveled 162 miles

Finally we add both traversed distances:

$d_{t}=187.5+162 \\d_{t} =349.5\\$

So , he traveled a total of 349.5 miles.
