Comparing Race Finishing Times

Hard Arithmetic Fractions, Decimals, And Percents

Consider the following situation involving fractions:

Mike and Anna are running a 5-kilometer charity race. Mike can run at a speed of 8 km/h, while Anna runs at a speed of 6 km/h. However, Anna stops to take a break that lasts for 10 minutes before she continues running. Calculate the time it will take each of them to complete the race, and then compare their finishing times.
Let:

  • Quantity A: The time taken by Mike to complete the race.
  • Quantity B: The time taken by Anna to complete the race (including her break).

Use the formula for time, which is given by:

$$ ext{Time} =\frac{ ext{Distance}}{ ext{Speed}}$$
