Question

How much metres per second did the cyclist travel from 8 a.m. to 10 a.m? (*TIP: 2 hours = 7200 seconds, 2 km= 2000 m). Give the formula used, show your working and round off your answer to two decimal places. Don't forget the unit!

Answer 1

`Speed = 0.28m/s`

Explanation:

Your question seem incomplete; however, I'll assume the given tips as the usable parameters.

Given

Distance = 2km

Time = 2 hours (8am to 10am)

Required

Calculate speed (in metres per seconds)

Speed is calculated as follows:

`Speed = (Distance)/(Time)`

Substitute 2 km for distance and 2 hours for time.

`Speed = (2km)/(2hr)`

Convert km to metres an hr to seconds.

`Speed = (2000m)/(7200s)`

`Speed = 0.277778 m/s`

`Speed = 0.28m/s` (Approximated)

Hence, the cyclist travels at 0.28m/s
