The Running time in distance of 2 kids are represented by the following equation and graft Cathy.Demonas 3.4t

Question

william:
D(distance in m)
The variable t represents the time( in seconds) and d represents the distance in meters.Who is faster and by how many meters per second m/s faster?

Answer 1

To compare who is faster, we need to look at the coefficients in front of t in the equations given for Cathy and William.

For Cathy:
Distance (D) = 3.4t

For William:
Distance (D) = t

Since Cathy's coefficient in front of t is 3.4 and William's coefficient in front of t is 1, we can conclude that Cathy is faster.

To find out how much faster Cathy is, we can simply subtract the coefficient of William's equation from Cathy's coefficient:
3.4 - 1 = 2.4

Therefore, Cathy is 2.4 meters per second faster than William.
