Let the first speed = x and distance =50miles.
Time = Distance / speed
T = 50/x
The second speed = 3x
Distance =300 miles
T= 300/3x =100/x
Given two fractions with equal denominators the fraction with the largest numerator is the largest hence :
The new time is more than the old time.
Time = Distance / speed
T = 50/x
The second speed = 3x
Distance =300 miles
T= 300/3x =100/x
