Clara cycles at a constant speed of 5 meters per second from west to east along a path. She passes a road sign during her ride. If t represents the number of seconds since Clara was 13 meters east of the road sign, write an expression to represent Clara's distance east of the road sign.

Distance Clara is East of the road sign = _____meters.

Answer: d(t) = 5m/s*t + 13m

Step-by-step explanation:

We have the relationship:

Distance = time*speed.

We know that the speed is 5 m/s and that t represents time in seconds.

then:

distance = 5m/s*t

We know that at t = 0s, Clara was at 13m pass the sign, then we have a y-intercept of b = 13m

So we can write the distance of the road sign as a linear equation:

d(t) = 5m/s*t + 13m

The distance Clara is from East of the road sign is given by the expression:

d = 13 + 5t

The speed at which Clara was cycling, v = 5 m/s

The time since Clara was 13 meters east of the road sign = t

The initial distance of Clara, [tex]d_0=13m[/tex]

Distance = Speed x Time

Clara's distance at t seconds, [tex]d_t=5t[/tex]

Clara's distance east of the road sign = Clara's initial distance + Clara's distance at t seconds

[tex]d=d_0+d_t\\\\d=13+5t[/tex]

Therefore, the distance Clara is from East of the road sign is given by the expression:

d = 13 + 5t
