Question

Mindy left at 8 a.M. And will arrive at 1 p.M.; jelly left at 8 a.M. And will arrive at 2 p.M. How many miles is the trip if Kelly is traveling 10 miles per hour slower than Mindy

Answer 1

Answer:

300 miles

Step-by-step explanation:

The distance equation is D = RT

Where

D is the distance

R is the rate

T is the time

Mindy

8 am to 1 pm = 5 hours

Kelly

8 am to 2 pm = 6 hours

Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "

Now using the distance equation, we can write:

Mindy >>> D = RT >>> D = 5m

Kelly >>> D = RT >>>  D = 6(m-10) >>> D = 6m - 60

Since both the distances are equal, we can write:

5m = 6m - 60

m = 60

We want the distance, we know:

D = 5m

D = 5(60)

D = 300 miles

The distance is 300 miles
