Science 7 Q3 Review 3

A cyclist can travel a distance of 240 kilometers in 15 hours. What is the average speed of the cyclist?Which among the given information is the time?

• 240 kilometers

• 15 hours

• 240 km divided by 15 hrs

• 15 hrs divided by 240 km

A cyclist can travel a distance of 240 kilometers in 15 hours. What is the average speed of the cyclist?Using the formula v = d/t, which of the following must be done to solve the problem

• 15 hrs divided by 240 km

• 240 km plus 15 hrs

• 240 km divided by 15 hrs

• 240 km multiplied by 15 hrs
