Nancy and Matilda will meet in 3 hours.
Step-by-step explanation:
Given,
Distance to cover = 60 miles
Speed of Matilda = 12 miles per hour
Speed of Nancy = 8 miles per hour
Combined speed of Nancy and Matilda = 8+12 = 20 miles per hour
Let,
x be the time taken by them
Distance = Speed * Time
[tex]60=20*x\\60=20x\\20x=60[/tex]
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{60}{20}\\x=3[/tex]
Nancy and Matilda will meet in 3 hours.

In 3 hours Nancy and Matilda meet.
Given
Nancy and Matilda are 60 miles apart, cycling towards each other on the same road.
Matilda rides 12 miles per hour and Nancy rides 8 miles per hour.
Speed is defined as the ratio of distance and time.
The time will take to meet Nancy and Matilda is given by;
[tex]\rm \dfrac{12}{8}=\dfrac{x}{60}\\\\8 \times x=60\times 12\\\\8x=720\\\\x = \dfrac{720}{8}\\\\x=90[/tex]
Therefore.
The time taken to meet them is;
[tex]\dfrac{12}{8}+\dfrac{90}{60}\\\\1.5+1.5= 3[/tex]
Hence, in 3 hours will they meet.
