Answer 2

Answer:

a) The mass of 4 identical watermelons is 3 kg. To find the mass of each watermelon, we divide the total mass by the number of watermelons:

Mass of each watermelon = Total mass / Number of watermelons

Mass of each watermelon = 3 kg / 4 = 0.75 kg.

b) The height of 5 identical shelves is 2 meters. To find the height of each shelf, we divide the total height by the number of shelves:

Height of each shelf = Total height / Number of shelves

Height of each shelf = 2 m / 5 = 0.4 m.

c) The speed of a cyclist is 15 km/h. To find the time it takes for the cyclist to travel a distance of 9 km, we divide the distance by the speed:

Time = Distance / Speed

Time = 9 km / 15 km/h = 0.6 hours.

d) The train traveled 20 km in 15 minutes. To find the distance the train traveled in 1 minute, we divide the total distance by the total time:

Distance per minute = Total distance / Total time

Distance per minute = 20 km / 15 minutes = 1.33 km/minute.
