Question

Спортсмен виконав три стрибки поспіль. Довжина першого стрибка дорівнює 3м,другого - на 28 см менша, ніж першого, а третього - на 3м 30см меньша ,ніж довжина перших двох стрибків разом.Яку відстань подолав спортсмен за три стрибки

Answer 1

1)300-28=272(см) довжина другого стрибка
2)300+272=572см) першого и другого разом
3)572-330=242 см) довжина третього стрибка
4)300+272+242=814см = 8м14см-подолав спортсмен за три стрибки

Answer 2

Calculation of the Distance Covered by the Athlete

To calculate the total distance covered by the athlete in three jumps, we need to determine the length of each jump and then sum them up.

Let's break down the information provided:

- The length of the first jump is 3 meters. - The length of the second jump is 28 centimeters less than the first jump. - The length of the third jump is 3 meters and 30 centimeters less than the combined length of the first two jumps.

To find the length of the second jump, we subtract 28 centimeters from the length of the first jump:

Length of the second jump = Length of the first jump - 28 centimeters

To find the length of the third jump, we subtract 3 meters and 30 centimeters from the combined length of the first two jumps:

Length of the third jump = Combined length of the first two jumps - 3 meters and 30 centimeters

Finally, to calculate the total distance covered by the athlete, we add up the lengths of all three jumps:

Total distance covered = Length of the first jump + Length of the second jump + Length of the third jump

Let's calculate the distances:

1. Length of the second jump = 3 meters - 28 centimeters = 2 meters and 72 centimeters. 2. Combined length of the first two jumps = 3 meters + 2 meters and 72 centimeters = 5 meters and 72 centimeters. 3. Length of the third jump = 5 meters and 72 centimeters - 3 meters and 30 centimeters = 2 meters and 42 centimeters. 4. Total distance covered = 3 meters + 2 meters and 72 centimeters + 2 meters and 42 centimeters.

Now, let's convert the lengths to a consistent unit, such as centimeters, for easier calculation:

1. Length of the second jump = 2 meters and 72 centimeters = 272 centimeters. 2. Combined length of the first two jumps = 5 meters and 72 centimeters = 572 centimeters. 3. Length of the third jump = 2 meters and 42 centimeters = 242 centimeters.

Finally, let's calculate the total distance covered:

Total distance covered = 300 centimeters + 272 centimeters + 242 centimeters = 814 centimeters.

Therefore, the athlete covered a total distance of 814 centimeters in three jumps.
