Question

За 4 часа теплоход прошёл 136км. За сколько часов он пройдёт с той же скоростью 238км.

Answer 1

136:4=34 км/ч - скорость

238:34=7 часов

Answer 2

To find out how many hours it will take for the ship to cover 238 km at the same speed, we can use the formula for speed:

Speed = Distance ÷ Time

We already know the speed (which is constant), and we need to find the time it takes to cover 238 km. Let's call the unknown time "T" (in hours).

We can set up a proportion using the given information:

Speed1 = 136 km / 4 hours Speed2 = 238 km / T hours

Since the speed is constant (the same in both cases), we can set up the proportion:

136 km / 4 hours = 238 km / T hours

To find T, we cross-multiply and solve for T:

136 km × T hours = 238 km × 4 hours

136T = 952

Now, isolate T by dividing both sides by 136:

T = 952 / 136 T = 7

So, it will take the ship 7 hours to cover 238 km at the same speed.
