Remy walked to a friend’s house m miles away at an average rate of 4 mph. The m-mile walk home was at only 3 mph, however. Express as a fraction a) Time Remy spent walking home.
b)Time Remy spent walking.

(Answer both (a) and (b).

a) m/4 miles per hour

b) 7m/12 miles per hour

Step-by-step explanation:

Mathematically, at any point in time;

Time = distance/speed

The distance here at any point is m mph

a) For the time spent walking home

Time = m/4 miles per hour

b) We add the time walking to the friend’s house and the time that it took to walk home

That would be;

m/4 + m/3 = 7m/12 miles per hour
