Mark do a company trip of 259.5 miles. He average 59 mph for the first part of the trip and also 57 mph because that the second part. If t

**gimpppa.org: he spends 1.5 hours on the very first part of trip and 3 hours on the second part of trip**

**Step-by-step explanation:**

Let x = the variety of hours for first part

Let y = the number of hours for 2nd part

Concept: rate × time = distance

----------------------------------------------------------------

x+y=4.5

59x+57y=259.5

-----

y=4.5-x

59x+57y=259.5

-----

59x+57(4.5-x)=259.5

59x+256.5-57x=259.5

2x+256.5=259.5

2x=3

x=1.5

4.5-1.5=3 hrs

On a long-distance biking trip, annike began biking at 7 a.M., and her mean speed was 11 miles per hour. Celia began at 8

**gimpppa.org:**

3.67 hours

**Step-by-step explanation:**

Speed is the proportion of distance to time, that is offered by the formula:

Speed = street / time

For annike her typical speed was 11 miles per hour and she began at 7 am.

You are watching: Phil smith is a car salesman

At 8 am (time = 1 hr i.e 7 am to 8 am) the distance she would have covered is offered as:

11 miles/hr = distance / 1 hr

Distance = 11 miles every hr × 1 hr = 11 miles

After 8 am, the distance traveled at time t is:

11 = distance/t

distance = 11t

Total street = 11t + 11

For Celia she began at 8 to be at 14 miles every hour, in ~ time t, the distance traveled is:

14 = distance/t

Distance = 14t

Given that both bikers travel the very same distance, hence:

14t = 11t + 11

3t = 11

t = 11/3

t = 3.67 hours
