Question

Alex must run 7 kilometres in an hour on the first day of his training. On the second day, the time was reduced by 20 minutes while the distance remained the same. What does this imply about Alex’s speed?

• A. Alex was faster on the first day.
• B. Alex needs to be faster on the second day.
• C. Alex should be running at the same pace on both days because the distance is the same.

Answer 1

The correct option is B Alex needs to be faster on the second day.

For a given distance, the speed is inversely related to the time taken to cover the distance. That means, if the time taken is reduced, then the speed will increase.
