Question

On a trip, a student drove 40 miles per hour for
2 hours and then drove 30 miles per hour for
3 hours. What is the student's average rate of
speed, in miles per hour, for the whole trip?​

Answer 1

Answer:

34 mph

Step-by-step explanation:

Average speed = total distance / total time

Total distance = ( 40 × 2 + 30 × 3 )

= 170 miles

Total time = 5 h

So, avg speed = 170/5 = 34 mph

Answer 2

If on a trip, a student drove 40 miles per hour for  2 hours and then drove 30 miles per hour for  3 hours. The student's average rate of  speed, in miles per hour, for the whole trip is 34​

Using this formula

Velocity=Speed ÷ Time

Where:

Speed= (40×2) +(30×3)

Speed=80+90

Speed=170

Time=2+3

Time=5

Let plug in the formula

Velocity=170÷5

Velocity=34

Inconclusion if on a trip, a student drove 40 miles per hour for  2 hours and then drove 30 miles per hour for  3 hours. The student's average rate of  speed, in miles per hour, for the whole trip is 34​
