Downhill RacerA snowboardertravels 105 metersin 7 seconds.A skier travels for4 seconds andcovers 72 metersHow far will a skier travel in 2minutes? Explain how you figured it out.

Answer 1

To be able to determine the distance that the skier travels, let's first determine its constant rate (speed).

A skier travels for 4 seconds and covers 72 meters.

Constant Rate (Speed):

`\text{ }\frac{\text{ Distance Traveled}}{\text{ Time}}\text{ = }\frac{\text{ 72 meters}}{\text{ 4 seconds}}\text{ = }18\text{ meters/second}`

Determining the distance covered in 2 minutes:

Step 1: Convert the time in minutes into seconds.

`\text{ 2 (minutes) x }\frac{\text{ 60 seconds}}{\text{ 1 (minute)}}\text{ = 2 x 60 seconds = 120 seconds}`

Step 2: Multiply the time by the constant rate (speed) of the skier.

`\text{ Distance Traveled = 120 (seconds) x }18\text{ }\frac{\text{ meters}}{\text{ (second)}}`
`\text{ = 120 x 18 meters}`
`\text{ Distance Traveled = 2,160 meters}`

Therefore, in 2 minutes, the skier travels 2,160 meters.
