The skier moved for 3 hours at a speed of 16 km / h, then went by car at a speed of 65 km / h. How much distance did a skier cover in a day?
To find the path that the skier has overcome, we use the formula: S = v * t, where v is the speed, t is the time;
Let’s find the distance that the skier covered on skis (v = 16 km / h, t = 3 hours);
1) 16 * 3 = 48 (km) skier covered in 3 hours;
Let’s find the distance that the skier traveled by car (v = 65 km / h, t – travel time);
2) 65 * t = 65t (km) traveled by car;
3) 48 + 65t (km) skier covered in a day;
Answer: 48 + 65t km.
