The song lasts 3 minutes and 27 seconds. If Rasmus' beloved has to get home before the song is over, and rides a bike at an average speed of 15 km / h, how far away must her work be from their home? Set up an equation that describes the problem where x is the distance between home and work.

Kindly check explanation

Step-by-step explanation:

From the question :

Duration, time, t = 3 minutes, 27 seconds = (3 * 60) + 27 = 207 seconds

Average speed = 15 km/h = (15*1000) /3600 = 4.16666 m/s

Let distance = x

Recall:

Speed = distance / time

Distance = speed * time

x ≤ (speed * time)

x ≤ (4.16666 * 207)

x ≤ 862.5 m

x ≤ (862.5 / 1000) km

x ≤ 0.862.5 km

1 is c

2 is a

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
