Question

Из села в город выехал мотоциклист со скоростью 53 км.ч. В то же время из города в село навстречу ему выехал велосипедист со скоростью 18 км.ч. Какое расстояние будет между ними через 3 часа если расстояние от города до села 220км

Answer 1

53*3= 159 км( проехал мотоциклист за 3 часа)18* 3 = 54 км( проехал велосипедист за 3 часа)159+54 = 213 км( всего они проехали)220-213 = 7 км( расстояние между ними)

Answer 2

220- (53 + 18) =149(км)

Answer 3

Problem Analysis

To solve this problem, we need to find the distance between the motorcyclist and the bicyclist after 3 hours. The motorcyclist is traveling from the village to the city at a speed of 53 km/h, while the bicyclist is traveling from the city to the village at a speed of 18 km/h. The total distance between the city and the village is 220 km.

Calculation

To find the distance between them after 3 hours, we can use the formula: Distance = Speed × Time

For the motorcyclist: Distance_motorcyclist = Speed_motorcyclist × Time Distance_motorcyclist = 53 km/h × 3 h

For the bicyclist: Distance_bicyclist = Speed_bicyclist × Time Distance_bicyclist = 18 km/h × 3 h

Solution

Let's calculate the distances for both the motorcyclist and the bicyclist:

Distance_motorcyclist = 53 km/h × 3 h = 159 km Distance_bicyclist = 18 km/h × 3 h = 54 km

Now, to find the distance between them, we can subtract the distance traveled by the bicyclist from the total distance between the city and the village: Distance_between = Total_distance - Distance_bicyclist Distance_between = 220 km - 54 km

Final Calculation

Distance_between = 166 km

So, after 3 hours, the distance between the motorcyclist and the bicyclist will be 166 km.
