The motorcyclist covered 240 km in 4 km. How many kilometers would the motorcyclist travel in the same time if he increased the speed by 8 km / h?
1 way.
240: 4 = 60 km / h – motorcycle speed.
If he increases the speed by 8 km / h, then his speed will be:
60 + 8 = 68 km / h.
It means that in the same time it will pass:
68 * 4 = 272 km.
Method 2.
If the motorcyclist’s speed increases by 8 km / h, then every hour he will travel 8 km more, and in 4 hours he will travel more
4 * 8 = 32 km.
Therefore, after increasing the speed, the motorcyclist will pass in the same time:
240 + 32 = 272 km.
Answer: 272 km.
