Answer 1

Answer: 1) 2.5 hours, 2) 130 miles

Explanation:

To solve both of these problems, let us remember the formula:

Distance = (speed) × (time)

1) Plug in the numbers into the formula:

150miles = (30miles/hour) × (time)

Divide both sides by 30miles/hour to solve for time:

150miles/(30miles/hour) = time

Simplify:

2.5hours = time

2) Susan's driving is broken into two parts with different speeds and time.

Solve the distance for first drive by plugging numbers into formula:

Distance = (40miles/hour) × (2hours)

Multiply:

Distance of first drive = 80miles

Solve for distance of second drive:

Distance = (50miles/hour) × (1hour)

Multiply:

Distance of second drive = 50miles

Add distance of first drive and second drive:

80miles + 50miles = 130miles

Answer 2

1) = 2hrs and 30mins

2) = 130miles

Explanation:

1) 60mi/hr, total driven 150miles

so at 120miles thats 2 hours. 30 miles is 30 minutes

60+60+30=150miles

2) 40miles/hr you drove 2 hours at 40 miles

40+40 =80miles

50miles/hr you drove 1 hour st 50 miles

40+40+50 = 130miles
