A truck driver has to make a delivery at a location that is 230.2 miles away. She

drives an average of 55 miles each hour

for 3.25 hours. If the truck driver

continues at the same speed, will she

make it to the location in the next

hour?

A Yes, she only has 51.45 miles to go.

® Yes, she only has 52.55 miles to go.

© No, she still has 63.45 miles to go.

D No, she still has 64.65 miles to go.

We want to see if the truck driver has enough speed to reach the destination or not. The correct option is A "Yes, she only has 51.45 miles to go."

So we know that she needs to travel a total distance of 230.2 miles.

Now, remember the relation:

Speed*time = distance.

And she travels at an average speed of 55 miles per hour for 3.25 hours, so she traveled a distance of:

(55 mi/h)*3.25 h = 178.75 mi

Then the remaining distance is just:

230.2 mi - 178.75 mi = 51.45 mi

Will she make it in the next hour?

Well, yes, she travels at 55 miles per hour and she has 51.45 miles remaining, so yes, she will make it.

The correct option is A: "Yes, she only has 51.45 miles to go."

Option A is correct

Step-by-step explanation:

Speed of truck = 55 miles/hour

Time taken = 3.25 hours

Distance = Speed × Time

× 3.25

But truck driver has to make a delivery at  a location that is 230.2 miles away.

Distance left to be covered by a truck driver = miles

So,

Yes, if the truck driver  continues at the same speed, she will make it to the location in the next  hour such that she only has 51.45 miles to go.

Option A is correct

45

Step-by-step explanation:

One hundred eighty minus ninety= 90

90 divided by 2=45
