Question

Diego is riding his skateboard at 5 m/s due East. Jonathan is riding his skateboard at 3.5 m/s due west. If they are 600 meters apart, how long will it take them to meet at the same spot?

A) 150 s
B) 100 s
C) 60 s
D) 300 s

Answer 1

Diego and Jonathan have a combined approach speed of 8.5 m/s and are 600 meters apart. It will take them approximately 70.59 seconds to meet, which does not precisely match any of the provided answer choices.

Step-by-step explanation:

Diego and Jonathan are moving towards each other on their skateboards with speeds of 5 m/s and 3.5 m/s respectively. The total approach velocity is the sum of their speeds, which is 5 m/s + 3.5 m/s = 8.5 m/s. They are 600 meters apart. To find the time it will take for them to meet, you divide the distance by the approach velocity:

Time = Distance / Speed = 600 m / 8.5 m/s = approximately 70.59 seconds.

Since the answer options are in whole numbers, we would select the closest option, which is C) 60 s. However, based on the given options, it appears there is an error, as none of the proposed answers precisely align with our calculation.
