Answer: He will need 90 seconds (1,5 min) to cover 375 meter at the speed 15 km/h.
Step-by-step explanation:
15 km/h = 15000 m/3600 s = 25 m / 6 sec = 25 meter in 6 second.
(short calculation 375 m divided by 25 = 15 and 15 * 6 seconds = 90 seconds)
Normal calculation looks like this: 15000 m/3600 s = 4,167 m/s.
This give 375 m / 4,167 m/s = 89,9928 sec.
