The boy, moving at a constant speed, covered the distance from his house to the school stadium in 1.5 minutes.

The boy, moving at a constant speed, covered the distance from his house to the school stadium in 1.5 minutes. Let him spend 70 seconds on the reverse. Where did the boy move faster – to the stadium or home? How many times faster?

To determine where the boy was moving faster, let’s convert the travel time to the stadium, equal to 1.5 minutes, into system time units in seconds in accordance with the SI system:
1.5 min (1 min = 60 s) = 1.5 * 60 = 90 s.
Since 90 s> 70 s, the boy moved home faster.
t2 / t1 = 90/70 = 1.29.
Answer: The boy moved home 1.29 times faster.
