Question

A girl rides her bike at 2.52 m/s on the way to her friends how which is 628 m away.

How long does it take the girl to get to her friends house?

Answer 1

Answer: 249 seconds

Step-by-step explanation:

Speed of bike = 2.52 m/s

Distance = 628 m

Time taken = ? ( let the unknown value be Z)

Recall that speed is the distance covered per unit time.

Hence, speed = Distance / Time taken

Time taken = Distance / speed

Z = 628m / 2.52 m/s

Z = 249.2 seconds (Round to nearest tenth i.e 249 seconds)

Thus, it takes 249 seconds for the girl to get to her friends house
