Answer 1

Ответ:

1. Объяснение:

Зная, что расстояние равно 300 м, умножаем 4 круга на 300 --- 4*300=1200 м

Чтобы найти среднюю скорость (м/с), нужно 1200 делить на общее количество секунд гонщика ---- 1200/63=19.05 м/с

Ответ:

Gollob: 1200/73=16.16 m/s

Olsen: 1200/64=18.75 m/s

Crump: 1200/78=15.38 m/s

2. Объяснение:

Зная среднюю скорость каждого гонщика (м/с), мы умножаем на 3.6 --- 19.05*3.6=68.58 км/ч

Ответ:

Gollob: 16.16*3.6=58.76 km/h

Olsen: 18.75*3.6=67.5 km/h

Crump: 15.38*3.6=55.68 km/h

P.S если что-то будет неправильно, извини:(

Answer 2

Let's go step by step to calculate the average speed in meters per second (m/s) and then in kilometers per hour (km/h) for Gollob, Olsen, and Crump based on the given information.

1. Calculate Average Speed in m/s:

   Given data:

   • Distance (d) for a lap: 300 meters
   • Time (t) for completing the 300 meters:
     • Gollob: 36 seconds
     • Olsen: 36.75 seconds
     • Crump: 37.5 seconds

   The formula to calculate average speed (v) in meters per second is: $v = \frac{distance}{time}$

   Let's calculate the average speed for each rider in m/s:

   • Gollob: $v_{\text{Gollob}} = \frac{300 \text{ m}}{36 \text{ s}}$
   • Olsen: $v_{\text{Olsen}} = \frac{300 \text{ m}}{36.75 \text{ s}}$
   • Crump: $v_{\text{Crump}} = \frac{300 \text{ m}}{37.5 \text{ s}}$

2. Calculate Average Speed in km/h:

   The formula to convert average speed from m/s to km/h is: $\text{average speed in km/h} = \text{average speed in m/s} \times 3.6$

   Now, let's convert the average speeds for each rider from m/s to km/h:

   • Gollob: $v_{\text{Gollob\_kmh}} = v_{\text{Gollob}} \times 3.6$
   • Olsen: $v_{\text{Olsen\_kmh}} = v_{\text{Olsen}} \times 3.6$
   • Crump: $v_{\text{Crump\_kmh}} = v_{\text{Crump}} \times 3.6$

You can perform the calculations based on the given information to obtain the average speeds in m/s and then convert them to km/h using the provided formulas. If you have the specific time values for Gollob, Olsen, and Crump in the table, please use those values in the calculations.
