Carl averaged 2m miles per hour on a trip that took him h hours
distance = (rate)(time)
So, Carl's travel distance = (2m)(h) = 2mh

If Ruth made the same trip in 2h/3 hours, what was her average speed in miles per hour?
average speed = distance/time
So, Ruth's average speed = (2mh)/(2h/3)
= (2mh)(3/2h)
= 6m/2
= 3m

Answer: E

Cheers,
Brent

Solution


Given
In this question, we are given
    • Carl averaged 2m miles per hour on a trip that took him h hours.
    • Ruth made the same trip in 2/3h hours

To Find
We need to determine
    • The average speed of Ruth, in miles per hour.

Approach & Working
Both of them are making the same trip, hence, the distance covered by both of them will be the same.
    • Distance covered by Carl = 2m * h miles = 2mh miles
    • Distance covered by Ruth = speed of Ruth * 2/3h miles

As the distance is same, we can write
    • 2mh = speed of Ruth * 2/3h
    Or, speed of Ruth = 3m

Hence, the correct answer is option E.

The distance of the trip is 2mh.

So Ruth’s average speed was:

2mh/(2h/3) = 6mh/2h = 6m/2 = 3m

Answer: E

Formula: Speed =\(\frac{Distance}{Time}\)

For Carl:

Speed = 2m miles/hour

Time = h hours

Distance = Speed * Time = 2m * h = 2mh miles

For Ruth:

Distance = Same as that of Carl = 2mh miles

Time = 2h/3

Speed =\(\frac{Distance}{Time}\) = \(\frac{2mh}{2h/3}\) = 3m miles/hour

The correct answer is E

Distance = S x T

Speed and Time are inversely proportional to each other, if distance is same.

Time changed from h hours to 2/3 h hours

hence, Speed will change from 2m miles per hour to 3/2 x 2m miles per hour

= 3m
