Answer 1

53+18=71 71×3=213 220-212=7

Answer 2

To find the distance between the motorcyclist and the cyclist after 3 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each person and then find the difference between them.

The motorcyclist's speed is 53 km/h, and the time is 3 hours. Therefore, the distance traveled by the motorcyclist is:

Distance_motorcyclist = Speed_motorcyclist × Time = 53 km/h × 3 hours

The cyclist's speed is 18 km/h, and the time is also 3 hours. Therefore, the distance traveled by the cyclist is:

Distance_cyclist = Speed_cyclist × Time = 18 km/h × 3 hours

To find the distance between them, we subtract the distance traveled by the cyclist from the distance traveled by the motorcyclist:

Distance_between = Distance_motorcyclist - Distance_cyclist

Let's calculate the distances:

Distance_motorcyclist = 53 km/h × 3 hours = 159 km

Distance_cyclist = 18 km/h × 3 hours = 54 km

Distance_between = 159 km - 54 km = 105 km

Therefore, the distance between the motorcyclist and the cyclist after 3 hours is 105 km.

Please note that the above calculations assume constant speeds for both the motorcyclist and the cyclist throughout the entire journey.
